Organizations are more concerned about computer security, as most information now is stored in databases, and most systems are connected to the Internet. Use of Intrusion Detection Systems (IDS) is one of the factors companies should consider when planning their information security policy. IDS is important to protect sensitive information, to meet laws and regulations and to prevent economic loss, although in some cases IDS implementation is no economically viable. To be able to determine if an implementation of an IDS is necessary some factors must be taken into consideration, such as advantages and disadvantages, economy, laws and regulations.
The basics of Intrusion Detection (IDS) and Intrusion Prevention (IPS) systems are essential to determine. A definition of an IDS is “the tools, methods, and resources to help identify, assess and report unauthorized or unapproved network activity” (Endorf, Schultz and Mellander, 2004, p. 4). There are three types of IDS, each of which functions differently, namely host-based IDS (HIDS), network-based IDS (NIDS) and hybrids. HIDS is software that scans all resources on a host for activity, and then compares against known threats. NIDS analyzes network packets on a network segment and either compare against known threats or analyze for patterns of malicious behaviour. A hybrid IDS combines these two methods (Endorf, Schultz and Mellander, 2004, p. 7). Two different analysis methods are used; rule-based detection analyses based on signatures, like virus scanning, and profile-based detection looks for abnormal data patterns (Endorf, Schultz and Mellander, 2004, pp. 16-17). Larger companies with sensitive information to protect should use hybrids to protect the network and those servers containing sensitive information. Ortega (2006, p. 6) states that signature-based solutions will not work for defending sensitive information, because hackers knows how to conduct new types of attacks.
Furthermore, according to Grimes (2004, p. 301) there are two generations of IDS. First-generation is based on accurate detection to give early warnings to security managers. Second-generation IDS uses more features to improve the accuracy and decrease the cost, and also implement some prevention mechanisms. Second generation gives the most protection, but for small organisations first generation will be sufficient and easier to implement and maintain.
Another consideration is a good management system. Grimes (2004, p. 317) says that instead of many management systems it is better to implement one system that can manage all security products in an effective way. Systems combining IDS and firewall technology should also be considered, especially for smaller organisations that have to save costs and manpower (Grimes.
The analysis will allow the NIDS to alert on activity which could be a sign of unauthorized access or malicious activity. The IT security team will check the alerts to determine if an event or incident has occurred. Similarly, an HIDS application will be installed on all servers and workstations. The HIDS application will analyze the servers and workstation and check the system logs to determine if any potential unauthorized or malicious activity has occurred and send the information to the NIDS for processing and alert creation.
Identity Management & Authorization is the ability to insure the person accessing the system is one, who they say they are, and two, authorized to access that program. In addition, this means terminating user account that are no longer authorized to access the system.
In the past few years, cyber-attacks have grown dramatically and it is up to Information security analysts to come up with solutions to prevent hackers from stealing vital information making issues for computer networks. Information security analyst’s main priority is to protect a company’s computer system from getting attacked by hackers. It takes a couple of things to become an ISA, but it’s a well worth and well-paying job.
The Aim Higher College’s system administrators and network engineers have described seeing some strange behaviors such as high levels of traffic from many hosts that are causing system outages. The web servers of the college have been shutting down frequently by this traffic, it must be from a hacker group trying to attack the school with malicious software. I will review the network traffic from the college’s intrusion detection system and use an intrusion prevention system to block off these threats from the hackers.
The main purpose of National ID card system in a country is to develop nationwide security, decrease crime rate, reveal the terrorists, and guard against illegal immigrants. NID system has been used conducting regular official transactions between government agencies and citizens, with benefits claimed in the areas of convenience, cost saving or fraud reduction. NID could be a combination of the functions of a driver’s license, social security registration, immigration documentation, and other identification system. This is the latest idea on national safety and security issues. But there can be raised some questions regarding this system, is it a good idea? Does it make people happy? Will it be effectible in general life?
We are being hired as a consultant to help respond to a small medical office in which they learned that 10 of their employees have been victims of identity theft. The office has 55 total employees amongst two office locations. They have one workstation per employee and different kinds of computer operating systems in use. There is a mixture of Windows 7, Vista, and XP operating systems. The servers being used are Windows 2003 and 2008 versions. This is used for the billing system which hasn’t been updated to cloud services. As a consultant, I will try to help the business by looking at how their information was being received by the attacker, to prevent further attacks, and to check
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
As you can see with the numerous ways around intrusion detection systems, as with any network security system, there is no complete security solution. Even with this there will always be a need for intrusion detection systems. The best of which would be a combination of network and host based IDSs, in other words a hybrid IDS. These will give you the benefits of both worlds of IDS and allow for greater security. Whatever your opinion on which solution is right for you, intrusion detection systems are here to stay and are a valuable tool in network security.
Because of these advances, such as computers and internet, fake ID’s are becoming easier to get, and their quality is improving. Not too long after states find ways of making ID’s harder to duplicate, the counterfeiters are finding a way to make them. Fake ID’s no longer consist of scratching an 8 into a 3. These advances make it hard to tell apart fake ID’s from the real thing. Some websites sell fake ID’s from $50-5,000. Selling fake ID’s over the internet has increased greatly over the past few years.

Principle of Security Management by Brian R. Johnson, Published by Prentice-Hall copyright 2005 by Pearson Education, Inc.
When someone suspects that an unauthorized, unacceptable, or unlawful event has occurred involving an organization’s computer networks or data-processing equipment Computer security incidents are normally identified. Initially, the incident may be reported by an ultimate user, detected by a system administrator, identified by IDS alerts, or discovered
The overall recommendation of "…the use of such identification badges to all of our clients." sounds reasonible. A closer look at the conclusion that identification badges alone will resolve the greater issue of employee theft is difficult to support with the amount and type of data given. In today's complex business environment, an identification badge would not address much greater corporate assets and their protection. To the technology industry for ...
Network management planning and security planning involves identifying the best and most appropriate systems and hardware that the firm can use to better manage network and plan security systems. Therefore, the management required me to examine the best software and hardware systems in the market place that the company can adopt to enable it to manage the network and security. The management required me to advice on the implementation procedure of various plans that are going to be adopted. My responsibility also involved finding out or predicting the impact of the plan on the future operations. They required me to evaluate the challenges the company might face while adopting the changes in the network management plan and security plans.
The first thing that we must consider about Information Security is that there is not a final destination at which we can arrive. IT Security is an ongoing set of processes and activities that requires attention and expertise on a daily basis. It is important to understand that systems are not secured by themselves and it is our responsibility to maintain and improve them periodically as required. It is of vital importance to establish the appropriate mechanisms and requirements in order to support the company’s CIA triad. The following report will provide you guidance about auditing and hardening techniques applied though the 7 Domains by utilizing IT Security Best Practices.
