Computer Security Incident Response Team Essay Example for Free

Computer Security Incident Response Team Essay In the last decade, more and more companies have started to look into e-commerce to connect them to the infinite world of global suppliers, partners, consumers and much more. This boom in technology has placed multiple assets are risk from a security stand point allowing hackers/crakers and anyone on the internet to gain access to these network and gain information or try to jeopardize business to a point where it stand stills. Increase in Denial of service attacks, child pornography, virus/worms and other tools used by individuals to destroy data has lead to law enforcement and media to look into why and how these security breaches are conducted and what new statutory laws are needed to stop this from happening. According to CSI computer crime and security Survey 2007, the average annual loss reported by security breach has shot up to $350,424 from 168,000 the previous year. To add to this, more and more organizations are reporting computer intrusions to law enforcement which inclined to 29 percent compared to 25 percent the year before. 1] To be successful in respond to an incident, there are a few things that need to be followed: 1. Minimize the number of severity of security incidents. 2. Assemble the core computer security Incident Response Team (CSIRT). 3. Define an incident response plan. 4. Contain the damage and minimize risk. [3] How to minimize the number of severity and security incidents: It is impossible to prevent all security related incidents, but there are things that can be done to minimize the impact of such incidents: †¢Establishing and enforcing security policies and procedures. Gaining support from Management in both enforcing security policies and handling incide nts. Accessing vulnerabilities on the environment on regular basis including regular audits. †¢Checking all devices on certain time frames to make sure that all the updates were performed. †¢Establishing security policies for both end users and security personal and asking for security clearance each and every time an access is granted. †¢Posting banners and reminders for responsibilities and restriction of use of applications, and other systems on the network. †¢Implementing secure password polices thought the network. Checking log files on regular basics and monitoring traffic. †¢Verifying backups are done on regular basics and maintained in an appropriate manner. This would also include the new email backup policy laws. †¢Create Computer Security Response Team (CSIRT) [3] Security threat is the same for both large, small, and government organizations and therefore it is important that regardless of what the company has for its security measures, it also ha s a written document that establishes guidelines for incident response. Incident respond planning is a set of guidelines that document on security incident handling and communication efforts. This plan is activated when an incident that could impact the company’s ability to function is established. Computer Security Incident Response Plan (CSIRP) should contain the following: 1. Mission: Things the response team will be responsible for, including how to handle incidents as they happen and what steps are necessary to minimize the impact of such incidents. 2. Scope: this would define, who is responsible for which area of security, it can include things like application, network(s), employees, communication both internally and to the public and much more. . Information flow: How information will be handled in case of an emergency and how it will be reported to the appropriate authority, pubic, media and internal employees. 4. Services provided: This document should contain all the services that are either provided to the users or services that are used or bought from other vendors including testing, education, service provider issues to name a few. [2] The CSIRT team must contain several members including a Team leader which will monitor changes in individual’s actives and responsibility of reviewing actions. An Incident Lead, that will be dedicated as the owner of set of incidents and will be responsible for speaking to anyone outside the team while and corresponding changes and updates. A group of individual’s part of the CISRT team called members will be responsible to handle responsibility of the incident and will monitor different areas of the company. Other members of this team should include Legal help, public relations officers, contractors and other member of management both from business and IT that can help during security breaches. If an Incident has occurred, it is important to classify this as an incident severity. Most companies use between Severity 1-5. 1 being the highest and 5 being the research phase where no system or user’s are affected. For most system anything under Severity 3 is not a major impact of the system but if there is a system wide issue that requires immediate attention, a severity 1 or 2 would fall under the category of Incident response procedure and set up a high alert. The cost of an incident can be very high, depending on the loss of data, therefore identifying the risk and all the real threat fall under this category. Once the incident has been identified it should go into the assessment phase, where it should be determined if the system can be bought back up again and how much damage is done. If the business is impacted assessment should be done. The assessment includes forensic investigation usually involving a team of expert that look into the how many computer were affected, what kind of information was stolen or changed, entry level of attacks, potential damage done by incident, recovery process and the best way to assess this from happening again. The next phase of this is containment, which is the assessment of damage and isolation of other systems that can also be compromised including network. Backup of the system in the current state should be done at this time for further forensic investigation. Analyzing of log files and uncovering systems that were used like firewalls, routers should be identified. Any modification of files including dos, exe should also be carried out in this phase. Once all this is done, the next step is Recovery. Recovery is restoring clean data back the system so it can perform is function as required. After installing last good backup, it is important to test the system before putting this in production again. Further surveillance of network and application should be set in place as intruders might try this again. Every company today, weather small or big needs an incident response unity to defend itself against predators on the web. The government agencies has set some rules and regulations on such standards and are required that company follow these standards to avoid further disruption of the service. This becomes even more critical for companies that play important place in the economy like credit card, health, insurance and much more. Several regional companies today can help plan CSIRP plan that provide help creating a team of individuals that can act fast in such situations. The implementation of such plan cost less in the long run, when compared to companies that don’t have such response plan and loose data that is critical to their survival.

Cryptographic Protocols for Electronic Voting Essay -- Technology Elec

Cryptographic Protocols for Electronic Voting After some preliminary research into the subject of electronic voting [BARL2003], it became apparent that there may be reason to mistrust current electronic voting systems. Further, as I studied a variety of voting systems, I realized I had little confidence that any of them (even paper ballots) would be guaranteed to produce a perfectly accurate tally. In my previous paper [BARL2003], I suggested the following definition: "An accurate voting system counts all valid votes with minimal processing error such that the intent of eligible voters is reflected in the final tally." I believe it is important for a voting system to (a) minimize error, (b) count all valid votes, and (c) preserve the intent of eligible voters in the final tally. At least in theory, I believe that today's electronic voting systems are capable of counting votes with minimal processing error. Assuming that all parties involved in the process of creating an electronic voting machine perform ethically, and that enough time, money, and effort is expended to do the job correctly, it should be possible to create a system that processes each entry that was received by the system. However, even making those assumptions, it is not quite that simple. There may be many reasons that a valid entry is not received by the system. For example, voters may be confused by the systems and may not enter their selections into the machine they way they intended. The system may "crash" before reporting its results. An eligible voter may be denied access to voting machines during the election interval . As far as I have been able to determine, the process for deciding the validity of a vote is subject to interpret... .../www.notablesoftware.com/Papers/1002evot.pdf [MERC2003] Mercuri, Rebecca.

Power Of The Fourth Estate How Does New Media Coverage...

Power of the Fourth Estate: How does new media coverage on polarized criminal justice cases influence case verdicts, public opinion and policy in the United States? The disbursement of accurate information is vital for the sustenance of a healthy democracy. It ensures that its citizens are equipped to make responsible, informed decisions pertaining to matters that affect their daily lives. In the United States, the media is referred to as the fourth estate or fourth branch of government (alongside the legislative, executive and judiciary branches). The media has been used as a conduit to broadcast local, state-level, federal-level and international government and social affairs. It may also be used to endorse campaigns, report misuses of†¦show more content†¦The cases chosen were: The Casey Anthony trial, the McCarthy hearings, Megan Kanka’s law, the Central Park Five case and lastly, the Watergate scandal. Each circumstance providing ample evidence of how the media’s role in each instance served a major factor for which altered or contributed to the case’s outcome. On July 15, 2008 in Orange County, Florida, Cindy Anthony, grandmother of two year old Caylee Marie Anthony called emergency services to report her grandchild as missing. Cindy explained to the 911 dispatcher that she had not seen Caylee in over 30 days. Cindy Anthony also explained to law enforcement officials that her daughter Casey Anthony (mother of Caylee) had given several different explanations as to the toddler’s whereabouts. Upon several interviews with law enforcement, Casey also told detectives that her daughter had been kidnapped by her nanny a month prior, before finally admitting that she had not seen her daughter Caylee in weeks.[1] On July 16th, 2008, Casey was arrested and charged with first-degree murder. The quest for missing Caylee continued as the media was now alerted by the unusual details of the pending trial. Casey Anthony was the target for extreme public inquiry and for her actions following the disappearance of her two year old daughter Caylee. Despite not knowing where her child was, Casey indulged in activities such as getting a tattoo, partying and drinking, all of which was
