...SEC280 Week 6 Case Study Gem Infosys, a small software company, has decided to better secure its computer systems after a malware attack shut down its network operations for 2 full days. The organization uses a firewall, three file servers, two Web servers, one Windows 2008 Active Directory server for user access and authentication, ten PCs, and a broadband connection to the Internet. The management at Gem needs you to formulate an incident-response policy to reduce network down time if future incidents occur. Develop an incident-response policy that covers the development of an incident-response team, disaster-recovery processes, and business-continuity planning. Gem Infosys Incident Response Policy To ensure timely response to a network disruption, an Incident Response Team has been formed. This team comprises contacts in several departments throughout the organization. The following policy outlines who to contact and what steps to take in case of an incident involving network related tasks. Incident Response Team Contacts DUTIES TEAM MEMBERS EXTENSION Team Lead Edward Einright 7001 Network Analysts Dave Firuzio 7002 Paul Gerschadt 7003 Security Analysts Rob Jensen 7004 Natalie Pierson 7005 Legal Affairs Frank Saddich 7006 Public Affairs Michelle Davenport 7007 Duties Team members will establish and implement policies in the following areas: a) Worm response procedure b) Virus response procedure c)...

...Kent Johnson SEC280 Instructor: R. Booth Week 6 Case study Here at gem security, it is important for our network and its resources to be kept secure from possible intrusion from outside sources. Installing of an IDS policy is an important thing in keeping the network safe. Installing a Network IDS (NIDS) onto a network requires a significant amount of thought and planning. In addition to the technical issues and product selection there are resource issues, from product cost to manning the sensor feeds and supporting the infrastructure that must also be considered. When installing an IDS a policy needs to be developed to ensure responsibilities are clearly defined. This is especially important when delivering an IDS capability remotely or to another organization's network. On the subject of failing hardware, people administering the target network must be made fully aware that if network taps are used, even fail safe taps can take up to a second for the interfaces to re-negotiate and could potentially disrupt services, though recent improvements have reduced this latency considerably. If the network is remote then it is advisable for the policy to reflect that the target network manpower can be called upon for a predefined duration for power resets, etc. Attempting this retrospectively through contractual alteration, if required, can be expensive and time consuming. If you rely on the distant network for support, ensure you have a telephone authentication system...

...SEC280 Week 6 Assignment – Joseph Ercole Case Study: Creating an IDS Policy. As the need to secure corporate networks continually increases, the task of ensuring the security of sensitive company data so that it is not compromised becomes increasingly difficult with each day. Gem Infosys, a small software company, has decided to secure their computer systems. The organization uses ten PCs and a broadband connection to the Internet. The management at Gem needs to formulate an IDS policy. We need to identify the steps to be performed when formulating the IDS policy. One of the best ways to protect company networks and data from attackers is to have an Intrusion Detection System in place. Today, IDS’s are an integral part of many organizations’ network infrastructure. But having the IDS in place and not understanding why it’s in place, how it works or who will deploy and run it or how to respond in the event of an attack is counter-productive to its existence. This is why we need to formulate the IDS policy. Before the IDS is deployed, we will create a basic outline of what we are trying to accomplish with the IDS and from there, devise a strategy. So, what are we protecting the network from and how strict will we make accessibility? Sometimes beginning with the end in mind is a good way to execute the first step of any plan or strategy. Knowing how tightly or loosely you want to allow traffic to flow on the network in order to have better control over it is a good start. We...
