Failures in Design and Security Principles - 1347 Words

The most common threat to a companys information assets mainly come from human error, inappropriate disclosures, and sheer carelessness on the part of the companys employees. Hackers who do intentionally tamper with the companys network often do so because they are tempted by assets they know are poorly protected. Weak security policies present the image that a company does not truly value its assets, which in turn attracts the petty thief and curiosity seeker. Therefore, the preventive element of any network security system should include a strong and enforceable security policy for its employees to follow, re-enforced by a form of technical protection (Control Data, 1999). Firewalls, antivirus programs and packet filtering devices†¦show more content†¦The levels are minor, major and critical, with critical meaning immediate action is required. The only time the system alarm is when a critical error is detected. During normal operations, the technicians monitor Vital Suites display, looking for unusual events. These events can come as a serious of major alarms that occur only a one specific time of day or a continuous string of minor alarms. These events can indicate subtle attempts at compromising the network. In the case of such events, the traffic is examined closer and any needed corrective action is taken at that time. Data collected by Vital Suite can also be used to expose points of vulnerability by looking for unused ports or poorly configured network devices. When a point of vulnerability is found, the technicians make any necessary system corrections. The true key to successful violation detection is not found with the sophistication of the tools used but in the skill of the people using them. Therefore the final element in establishing an effective detection system is creating a training program that ensures that the people monitoring the system know how to properly use the tools and how to best discover any attempt at attacking the network. Recovery No matter how well developed a network security system is, there still comes a time when the system is defeated. For this reason, a recovery plan must be established. The plan should provide for a process to regain control of the network,Show MoreRelatedSecurity Design Principles List And The Classic List Of 1975 Essay1335 Words   |  6 PagesSecurity is very important in any organization because one of the most significant values of an organization is its information in addition to that, its security is critical for business operations as well as its clients and customers.
