Yen sun to inaugurate operation at China plants
Aaron Lee, Taipei; Joseph Tsai, DIGITIMES
Wednesday 20 February 2019
Taiwan-based cooling reply developer Yen solar know-how will perceive its flowers in Dongguan quickly enter pilot creation for certification by means of its motor vehicle seller client and start mass construction in April with optimum means to achieve over one million gadgets a month. The web site may breathe particularly used to meet orders from China, while flowers in southern Taiwan should breathe serving consumers from Europe, the us and Japan, based on Robert Liu, universal manager of Yen solar's digital Cooling Division.
Yen sun registered consolidated revenues of NT$290 million (US$9.33 million) for January, rising 17.seventy five% on year. on account of fewer working hours as a result of the Lunar recent year vacation trips, the company expects the amount to slide on month in February, however to elect on up in March. Some market watchers predict Yen solar's first-quarter consolidated revenues to achieve a recent quarterly checklist with contributions from cooling and residential appliance items.
Yen solar is planning to expand means at vegetation in southern Taiwan and has built recent flowers in Dongguan, China to fulfill require from the car sector.
Liu brought up that carriers are turning to headquarters of attention on designing cars with lighter weight and less dash consumption and the approach is anticipated to set off a wave of require for heat dissipation options. Yen sun's visibility of such orders has already reached the conclusion of 2019 and the enterprise is already starting to design automobiles with customers for the subsequent three years.
presently, Yen solar has 65% of its revenues contributed by means of its cooling reply products with the ease coming from home appliance items. Of the revenues from cooling solutions, 38% are from automobile cooling and others workstation cooling.
currently, the flowers in southern Taiwan are capable of configuration 120,000 contraptions of cooling fanatics a month and the company is looking to raise the quantity to 300,000 contraptions before the cessation of the primary half.

And it’s off to an excellent birth for the solar Flyer 2 and its Siemens electric motor. The electric powered plane (e-plane) effectively achieved its first peep at various flight with the brand recent electric motor.
Bye Aerospace has been busy the past few years furiously working on this e-aircraft, so the executives engineers possess to breathe over the moon about the electric solar Flyer 2 completing its first respectable flight on February eight at the Centennial Airport, south of Denver, Colorado.
above all, Bye Aerospace is focusing its flight checking out on its propulsion equipment, envelope expansion, and techniques optimization. it is using a fifty seven lb Siemens SP70D electric motor, which has a max dash of 89.5 kW (a hundred and twenty HP) and a ceaseless dash atmosphere of as much as 70 kW (94 HP).
Bye Aerospace is setting up a few plane within the sun Flyer household — a 2-seat sun Flyer 2 and a four-seat sun Flyer 4, as they in the past said. The company wants to construct the first FAA-licensed, functional, all-electric powered airplanes to serve the flight practicing and common aviation markets.
Bye Aerospace competes with one more e-plane maker, Pipistrel, which has its Alpha Electro. dwell tuned for an interview with Pipistrel pros, as well as electric powered flight leaders at Bye Aerospace and Siemens.
The FAA gave the solar Flyer 2 a ways 23 certification closing year in 2018. Bye Aerospace will continue checking out of the solar Flyer 2 prototype through 2019.
related to this examine flight, in line with George E. Bye, CEO of Bye Aerospace: “The airplane performed exactly as planned. My due to the total Siemens crew for their participation as they enter this subsequent, essential flight check section of sun Flyer 2 with the Siemens electric propulsion device.”
The company also has 2 different projects, the Stratoairnet, a solar-electric powered Unmanned Aerial automobile (UAV) and the secretive Falcon UAV developed by secretive Falcon u.s.a.applied sciences which you can find prerogative here.Siemens’ chic position in the electric Aviation business
Siemens and its electric motors play a gargantuan role in the electric powered aviation world, a capable deal devotion Bosch pushed alongside the electric powered bicycle (e-bike) world. Siemens has already verified 260 kW electric motors earlier than on European e-planes. The definitely respectable news is that it’s establishing propulsion technology with a whopping 10MW of energy, for commercial electric plane for the aviation transport sector. to this point, Siemens electric motors possess set at the least two velocity facts — the primary aero tow via an electrical plane and a recent world climb checklist with an altitude of three,000 meters in 4 minutes and 22 seconds.
Dr. frank Anton, government vice chairman and Head of eAircraft, Siemens delivered:
“This successful peep at various flight is a arrogant second for the Siemens and Bye Aerospace teams and marks a milestone in bringing the age of electric powered flight to life. The Siemens electric powered propulsion gear offers a clear, cost-effective and secretive propulsion election to the flight training market devoid of compromising performance or safeguard.”electric Airplanes Are closer Than You think
The electric vehicle (EV) rEVolution has been significantly underway for the past decade, but generally focused on land-certain motors. The maritime and aviation industries are now working extra significantly on the electrification of vessels and plane, however in a unique approach from the automotive industry. but don’t breathe fooled just because you don’t yet perceive a Tesla plane — Bye Aerospace and a yoke of other electric flight pioneers are bringing electric powered urban air mobility near us.

One of the driving forces behind the mosey to storage district networks (SANs) has been the increasing significance and size of enterprise databases. As databases grew, administrators found that the only pass to efficiently manage and expand database storage is to tap into the flexibility of SANs. However, with the expanded exercise of databases on storage networks, storage administrators now must deal with recent performance, backup, restore and management issues-not to mention how to accept along with the database administrators (DBAs). Here's what storage administrators should know about marrying a database to a SAN.Oracle's Storage Push In a mark that database vendors are increasingly alert of how necessary the storage behind their databases is, Oracle recently announced that it is launching a storage initiative, which seeks to combine the company's various individual storage initiatives into a strategic push to focus on how Oracle runs on storage. Oracle's initiative includes programs to certify interoperability of hardware components within an Oracle environment.
According to Allen Hoke, technical director, system platforms division of Oracle, "This program focuses on storage technology at a elevated even vs. their former focus on specific areas such as backup or particular storage hardware or storage management technology." In addition, Hoke says, "In order to provide a capable customer experience, they are teaming with their key OS, server hardware and storage partners to provide a remote advocate strategy, aligned between us and their partners."
At this time, Oracle's partners comprehend EMC, HP, Hitachi, Network Appliance, Legato, Sun, and Veritas.
A few years ago, not many database applications ran on anything but direct-attached storage (DAS). As databases grew, however, administrators looked for easier ways to deploy storage and began using network-attached storage (NAS) to more easily scale their databases. With the advent of SANs, administrators are now finding that storage networks can provide even better performance for the most demanding transaction-oriented, elevated volume databases.
Today, database applications are starting to mosey from DAS to SANs. The reasons: increased ease and precipitate of backup, better scalability, as well as enhanced reliability and performance. For many applications, a SAN is the only option available that provides the required performance.
Harold Durnford, a storage administrator at Royal Bank Canada, Toronto, Canada, says, "We've had Oracle, Sybase, UDB, and Informix on a SAN for quite some time. The reason they looked at storage district networks was the challenge of sharing big storage subsystems." In addition, he says, "It wasn't just a distance limitation, but also true estate. With SCSI, they found they quickly ran out of SCSI ports on their arrays before they ran out of storage. They used the SAN to address fan-out."
Marty Ward, vice president of product management at Veritas has also seen this, and says, "Database users are very focused on scaling up and scaling out, which you can't execute with dedicated storage."
Bob Rogers, chief storage architect at BMC says, "Consistent even of performance is driving people to storage district networks, as are better attribute backup and recovery tools. Those are complete very sturdy motivators to fade to a SAN environment, which is why very big customers possess embraced SANs and Put databases on them quite early."
Jim Booth, director of systems engineering at CreekPath, agrees, saying, "People are moving to SANs primarily to accept the performance. You can certainly implement a database on either NAS or a SAN. However, if you're doing it on a SAN, you accept consistent throughput. Though it might breathe harder to manage, a SAN provides better performance and availability."
SAN configurationsA typical SAN configured for a database application includes database servers clustered for reliability and attached to a central network. At a minimum, two separate database servers are clustered together for redundancy, with dual redundant Fibre Channel (FC) fabrics connected to redundant RAID controllers. In many cases, path failover software such as EMC's PowerPath or Veritas' Dynamic Multipathing (DMP) is used to ensure multiple paths to the storage array, in conjunction with high-availability storage arrays and cluster software.
Michael Leo, a database administrator at Minneapolis, MN-based Caribou Lake Software, a consulting hard which helps companies manage their systems, works with a big medical devices manufacturer replacing legacy Alpha VMS systems with Solaris machines, connected to an EMC Symmetrix SAN. "Everything is striped and mirrored [1+0]. They are using the SAN for development, production online transaction processing [OLTP] and production reporting-a data warehouse of the production database used for reporting. Each database is in the 100GB to 200GB range. They possess two copies of the OLTP database-one is a replicated smarting standby, " says Leo. The systems precipitate Computer Associates' Ingres database.
"To back up the database, they are using the SAN for disk-to-disk backups. They then exercise Veritas' NetBackup and a separate backup LAN to backup the SAN. To manage the disk space on the Sun, they exercise Veritas in combination with EMC's SAN management tools," says Leo.
Database performanceOptimizing database performance has traditionally been done by configuring how and where tables and logs are stored, as well as configuring disks and storage for database access patterns. Database data is broken down into two principal types of data: tables-the actual data which is stored in the database-and logs, which are logs of the transactions to a database. Transaction logs are faultfinding for recovering a database if there's a failure and are also used for replicating databases. Many databases can also exercise their own aboriginal file systems to maximize performance, maintain control over tables and avoid potential performance penalties imposed by file system buffering. Aside from quick storage, CPU and memory, administrators possess paid a lot of attention to balancing precipitate vs. redundancy of data.
Database and storage administrators possess carefully selected RAID configurations-for example, using RAID 0+1-both mirroring and striping-in order to gain the greatest read performance from their hardware without losing redundancy. While RAID 5 provides for redundancy at a benign of lower cost, most database vendors today recommend RAID 0+1 for tables as well as logs and only recommend RAID 5 for less performance-critical backup volumes. Caribou Lake's Leo says, "Performance is highly topic upon how you configure the SAN. They possess seen very capable performance for databases with RAID 1+0 sort configurations. They possess also seen decent performance for RAID 5, unless the RAID 5 is in rebuild. If the RAID 5 is in rebuild, write performance is so bad, the system may as well breathe down."
To further optimize access times and data throughput, database administrators possess to also configuration confident that tables and logs never participate the same spindles on a disk. John Eisenschmidt, a DBA at the American Association for the Advancement of Science, Washington, D.C., says for his ultimate install of Oracle, "We made confident not to Put the index tablespaces with the data tablespaces to improve read performance, and Put the archive logs and redo logs in different places to equipoise write operations." Eisenschmidt manages about 2.5TB on a SAN filesystem on Xiotech hardware, used for storing user files, though he still runs his databases on raw dedicated disk.
However, with the advent of SANs and virtualized storage, administrators no longer possess that even of control of data placement. According to Bob Rogers, chief technology officer of BMC Software, "Most DBAs are absolutely convinced that file placement is an absolutely faultfinding issue, however, most disks today are virtualized-and users don't possess a clue where things are physically located."
Luckily, the precipitate and manageability of storage possess improved the situation, despite the loss in control. Rogers says, "Today, you can accept a much more consistent even of performance by going to very big arrays such as those from EMC, IBM, and HDS than you could going to direct-attach disk."
Enter virtualizationDespite virtualization's equable march into storage systems, most vendors and users assume that some control is still needed to fully optimize database access. Oracle's Hoke says, "One of the gargantuan atrocious things that can betide with virtualization is that you can possess two tables related in your traffic application, with a elevated even of traffic in inescapable rows of those tables."One pass to Dramatically multiply Database Performance Question: "Have you approach across some hard numbers and performance figures for the exercise of RAID (at any level) in the database environment?"Securing PDAs with sensitive data - or access to it - should breathe taken seriously. Basically, you need to apply the same rigor to PDA security that you would to any other enterprise-class device, with a limpid security policy and a uniform suite of security software. deem the following:Chris Poelker: Database application performance shouldn't only breathe looked at from an I/O standpoint, but first and foremost from a design perspective. For example, at one customer site, they were using SQL server in a three-tier Web application, where the Web pages were built dynamically from the database. The design used energetic server page scripts in the application tier to query the database for results and the results were then sent to the Web server to build the dynamic pages.By moving to SQL - stored procedures at the database level, and tuning the indexing methods - and a slight schema redesign-performance improved by over 800%, complete without even touching the back cessation I/O. Never hurl hardware at a impecunious design as the return on investment is never as capable as taking the time to rethink the original design.Here's the some things to execute for capable I/O performance:1) exercise a lot of spindles. If you fade to and peep at the specifications on the designs to achieve maximum database performance, you'll notice they exercise hundreds of drives. By a lot of spindles, I don't involve big RAID sets. You should concatenate many smaller RAID sets into a solitary LUN either by using host software or LUN virtualization within the storage hardware, if it has that capability.2) exercise low latency paths to storage. Fibre Channel uses a packet-based network, which allows for a complete duplex backend. On a SCSI bus, only one thing can betide at a time. Using dual-pathed Fibre disks, you can possess a read command on one side and a write command on the other side of the disk being queued at the same time.3) Spread the I/O load as much as possible. exercise many HBAs in the server that are load balancing your I/O across complete the paths. Tools devotion Veritas' Volume Manager or Solstice Disk Suite can cheer execute this by creating a solitary LUN from many spindles on each path. By using 2Gb paths and four HBAs, you can accept close to 800MB/sec to the LUN.4) exercise the proper RAID even for the log and database. Best exercise here is log files should breathe on RAID 0+1 (RAID 10) and databases on RAID5 (RAID 0+1 can breathe used on the database for better performance if your budget allows for it).Performance. Today's hard drives can achieve a sustained throughput of between 30MB/s and 50MB/s and 120 to 140 IOPS (I/Os per second) per spindle. The performance depends on the drive electronics, onboard cache size, rotation precipitate (15,000 RPM is better than 7,200 RPM of course) and maximum search latency. If you partition your RAID set into little partitions, and locate your data on the outer cylinders, your performance will fade up substantially. Doing this reduces the search time for a particular partition. Now just add up the number of spindles to motif out your maximum IOPS. motif 1680 IOPS using 14 spindles on one HBA, or 3360 IOPS using 2 HBAs to 28 disks doing 64,000 sequential I/O(random I/O will breathe less). Changing the shroud size of the transfer will either multiply MB per second (throughput) or IOPS. Smaller blocks configuration IOPS fade up, larger blocks configuration throughput fade up.These numbers are for direct I/O, sense no cache in front of the drives. Adding cache can multiply performance dramatically. I possess seen 33,000 IOPS on a solitary LUN during 100% cache hit. So, if you want the best I/O performance available, exercise a solid-state disk.Christopher Poelker is a storage architect at Hitachi Data Systems. He answers readers' questions on "Ask the Expert" at SearchStorage.com.
According to Hoke, a capable database administrator will try to spread those tables across multiple devices, so he doesn't create hotspots, and also for availability. However, with virtualization, those two tables may breathe inadvertently placed on the same disk, because virtualization masks physical locations. "Virtualization is mighty for provisioning storage because it's facile to mosey data and add disks. But with a database, because of performance issues, there are potential drawbacks," Hoke says.
CreekPath's Booth agrees: "File placement is still absolutely necessary with a SAN, although disks possess gotten faster. It still comes down to laying down data on a spinning disk, and not putting redo logs and indexes on the same physical drives. That's why it's necessary for tools to perceive complete the pass down to the spindle level, so that when they're laying down data it's not stepping on its own toes."
Marty Ward, director of product marketing at Veritas concurs, although he doesn't assume administrators need to breathe directly concerned with where data is, "DBAs don't need to breathe considered about which spindle disk data lies on. They bewitch care of that for them. Their ratiocinative volumes allow them to mosey data around on-the- soar to adjust hotspots, even while running." Other vendors are also announcing tools in this area.
Durnford sees things the same way. "Using JBOD, you're much more sensitive to placements [hotspots]. However, using storage arrays, they exercise their technology to mosey storage around while running to purge hotspots, so that the server doesn't really need to know the physical storage location," he says. Durnford uses built-in tools on his Hitachi, IBM, and EMC arrays to deal with hotspots on his volumes.
SAN issues"In the musty days of NFS [network file systems], due to want of availability capabilities for Oracle, their customers saw storage corruption," says Oracle's Hoke. Because of those issues, Oracle's validation program for network-attached storage arose out of concern about the nature of NFS," he says.
In a SAN, storage just looks devotion a SCSI disk-reducing a number of the headaches that came with putting databases on network-attached storage, since the interface is identical to that of SCSI. Unlike NAS - with storage networks Oracle has left it to their storage partners to qualify HBAs - switches and front-end storage FC adapters. Hoke says that with a SAN, "We possess not identified anything needing validation."
However, it still takes some labor to accept SANs performing prerogative for databases. DBA Eisenschmidt - despite running a SAN for his applications and file systems -is skeptical of using SANs for his database storage. "Our SAN, devotion many I've seen, is optimized for storage capacity and file serving. While Oracle uses Xiotech's Magnitude in their test labs, I was pretty unhappy with the transaction performance they were able to accept out of it."
CreekPath's Booth says, "The biggest issue with databases on a SAN is maintaining consistent throughput and access on a database while running other application sharing the same SAN."
Caribou Lake's Leo agrees, saying, "SANs often reclaim an enterprise money by sharing I/O capacity across departments. But sharing I/O resources between the user files of one department and the DBMS storage for another is awful. The database management system's I/O characteristics are completely different than the user data files, and cache coherency becomes an issue."
Royal Bank of Canada's Durnford has opted for separate storage networks to resolve some of these problems. He says, "For tape, we're looking at a separate tape SAN. The issue there is database traffic is very time-sensitive, where tape traffic is very backup-oriented. Though you might assume it's time shifted, we've found there's overlap."
The other issue most DBAs mention is the complexity of managing storage networks, which are typically managed by separate storage infrastructure staff. "A lot of progress has been made in the ultimate yoke years, but most system administrators want SANs that are easier to administrate. I want a more accountable SAN whose caching I'm not unafraid to rotate on," Eisenshmidt says.
Leo says that when you Put a database and storage together, "You realize that your SAN management team must labor closely with the DBMS team. They possess seen situations where SAN managers possess decided to change the SAN configuration because it seems wasteful or odd, not realizing how carefully tuned the setup was."
CreekPath's Booth also agrees, maxim that while careful tuning of how storage is configured can purge sharing issues, "Both DBAs and storage administrators need to breathe on the same page."
Despite the issues, some users possess had mighty success running SANs with their databases. John Brooks, vice president of storage engineering at Cleveland, OH-based National City Bank, runs an 18TB SAN, which is based on Brocade switches with IBM and Hitachi arrays. "We possess no issues with running on a SAN. Not even performance issues. It just seems to run," he says. Asked if he does anything special for databases, he says "For SQL and Oracle databases, they hurl it on the SAN." Brooks attributes the want of issues to the relationship he has with his storage vendors. He says, "We execute a lot of research, primarily in the interoperability district that might account for the want of issues. They labor very closely with their storage vendors to ensure certification and supportability of the environment, in case issues execute arise."
Tools and techniquesBecause SANs' recent role as the primary storage for databases, there's now a need for improved tools and software to manage the combination of database applications and storage. "It would breathe nice if vendors could provide some sort of management tool to track why a SAN partition was configured in a inescapable way, thus preventing the loss of historically significant details when SAN management changes hands," says DBA Leo.
"If I could possess anything from a SAN to configuration it better for a database, I'd put a question to the vendors to write better drivers. Most of the drivers I've seen and worked with just parade the OS the drive is gone when the SAN disconnects, instead of perhaps telling it to wait or trying to free the process," Eisenshmidt says.
Some vendors seem to breathe listening and are increasingly focusing their efforts on getting their database to precipitate better on SANs, and their storage and infrastructure to better advocate databases. Take, for example, Oracle's Hardware-Assisted Resilient Data (HARD) initiative (see "Oracle's storage push"). Oracle's Hoke explains, "We're working with hardware partners to verify that when Oracle data is transferred to a disk it can breathe read. This sounds simple, but with storage management and storage virtualization in storage networks, there are lots of cooks in the broth."
Part of Oracle's hard initiative, EMC's Oracle Double Checksum tool offers the ability to verify Oracle data as it is written to arrays in microcode, ensuring that corrupted data is never written to disk. Competitor Hitachi Data Systems has also announced advocate for the initiative, with a microcode-based verification of Oracle data in their Lightning 9900V product.
EMC also offers its Symmetrix Optimizer, which makes recommendations to administrators on where to rebalance data-a must for administrators looking for smarting spindles. EMC has a close partnership with Oracle, including a dedicated engineering team at Oracle Redwood Shores. Chuck Hollis, EMC's vice president of products and markets says, "We possess 12 to 15 engineers inside Oracle, some dedicated to interoperability, and the ease to feature exploitation such as their Double Checksum product and integration between Oracle and their replication products."
Veritas also offers a host of products designed to labor with databases and SANs. The company's Database Edition products for Oracle9i, IBM DB2, and Microsoft Exchange, including mirroring, backup, replication and clustering features designed for those databases. According to Veritas' Ward, an upcoming release of the company's storage resource management product, "will map data complete the pass from a database environment in Oracle or Exchange, through files, complete the pass down to disks to display you which spindles and extents the data is written to."
BMC offers its PATROL for Storage Management product. BMC's Rogers says, "When you're working with Oracle or Sybase or Microsoft SQL server and even Exchange, they can expose that from a database perspective. For example; they can expose an Oracle instance that is on a Solaris box and attached to a SAN, and perceive where it is spread about. They can expose that through a topology manager-all of the connections, solitary points of failure, and the pass the database is laid out on disk."
Despite complexities of managing databases running on storage networks, the benefits are clear. For big databases, there's really no better option that a SAN because of the even of performance, consistency, redundancy, and scalability that a storage network provides. Storage and database administrators alike are finding that the only pass to advocate their mission faultfinding applications is to deploy their databases on a storage network. With so much at stake, storage and database vendors will continue to labor more in tandem to configuration their products labor better together (see "Vendor independence: Are the trade-offs worth it?").
This article is the second in a succession that discusses a policy of security incident responses. The article describes the policy best practices and execution features — evaluation, containment, and eradication of and recovery from a security incident — for responding to a customer's incident within the policy scope.Like this article? They recommend
There possess been several large-scale worm attacks on the Internet since 1988 and highly visible and coordinated denial-of-service attacks in the ultimate few years causing billions of dollars in damage. These attacks bespeak that responding to such incidents is increasingly more complicated and requires technical knowledge, communication, and coordination among the staff responding to an incident, along with an adherence to applicable standards and policies.
A security incident response involves several aspects of preventive, detective, and recovery measures. A preventive measure primarily involves risk control that mitigates the effects or deters the happening of an undesirable event. Examples of preventive measures are passwords, keycards, badges, contingency plans, policies, firewalls, and encryption. A detective measure identifies the happening of an undesirable event. Examples of detective measures are visitor logs, audit trails, motion sensors, closed-circuit TV, and security reviews. Detective measures also provide a means for reporting the happening of events. A recovery measure is a risk control that will, in a traditional sense, comprehend control policies, processes, or mechanisms that restore the integrity, availability, and confidentiality of information assets to their expected state. Examples of recovery measures are weakness tolerance, backup, and catastrophe recovery plans.
Since the late eighties and early nineties, a substantial amount of information has been published on the topic of security incident response from the following organizations:
Australian Computer Emergency Response Team (AusCERT), http://www.auscert.org.au/
Brazil's Centro de Atendimento a Incidents de Segurança (CAIS), http://www.rnp.br/lang/cais_en/
Carnegie Mellon University's Software Engineering Institute's Computer Emergency Response Team/Coordination headquarters (CERT/CC), which was initiated by the Defense Advanced Research Projects Agency (DARPA), http://www.cert.org
European Institute for Computer Antivirus Research, http://www.eicar.org/
German Computer Emergency Response Team (DFN-CERT), http://www.cert.dfn.de/
Internet Engineering job force (IETF) in the configuration of RFCs, http://www.ietf.org/rfc.html
Purdue University's Computer Incident Advisory Capability (CIAC), which is funded by the Department of Energy, http://www.ciac.org/ciac
SysAdmin, Audit, Network, and Security, http://www.sans.org
U.S.'s National Institute of Standards and Technology (NIST), http://www.nist.gov
In 1990, NIST, in conjunction with CERT/CC, CIAC, NASA, and other agency response teams, organized a cooperative activity known as the Forum of Incident Response and Security Teams (FIRST) at: http://www.first.org
This coalition brings together a variety of computer incident response teams from governments, commercial organizations, and academic organizations. FIRST fosters cooperation and coordination in incident prevention, prompts rapid reaction to incidents, and promotes information sharing and learning among the members of its community.
": Executing a Policy" is the second of a succession of articles that discuss a security incident response policy and execution. These articles are not intended to comprehend complete of the material from the above efforts. They are intended to capture the salient points of the security incident response process and to present them in the context of a traffic entity that serves its constituents (that is, its customers).
The first article, "Responding to a Customer's Security Incidents—Part 1: Establishing Teams and a Policy," contains definitions of security incidents, security incident response, teams that typically are involved in an incident response, the pros and cons of the teams, and the scope and goals of the security incident response policy. In addition, it describes policy essentials for the notification aspect of a security incident.
This second article describes the best practices and execution of key policy features of responding to a customer's incident within the policy scope described in the first article. These features mainly comprehend evaluation, containment, and eradication of and recovery from a security incident. Subsequent articles will focus on incident follow-up, with a special stress on forensics, risk analysis, catastrophe recovery, and government and legal recourses, as well as proactive teamwork. The primary audience consists of computer security managers, security policy developers, system administrators, and other related staff, accountable for the creation or operation of a computer security incident response policy and service.
