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.

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
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.
Implement a system Intrusion Detection/Prevention System (IDS/IPS): - Make the investment in an IDS/IPS to distinguish and prevent potential system dangers. sensors ought to be circulated all through the system, with a specific focus on general society untrusted section. Take alerts very seriously.

The attacks highlight the shortcomings in the system, trace them and correct the problem. Almost all major IT firms, defense systems and Cyber related organizations imply these methods in their security prevention mechanisms.
Information security and risk has become a priority for organization vying to protect a network and organizational data from unscrupulous entities (Zhao, Xue, & Whinston, 2013). In the operation of systems and/or processes, theoretical frameworks may be used to assist organizations in the development of security control measures that support the denial of threats such as phishing attacks and rootkit installations (Sun, Srivastava, & Mock, 2006). In addition, Sun et al. (2006) summarized that theoretical frameworks assist in methodologies associated with the identi...
Information Security Analysts are the guardians of information systems, they arrange and execute efforts to establish safety to shield an association's PC frameworks and systems from invasion and cyberattacks. Analysts help companies avoid, screen and react to breaches and cyberattacks. Analysts have to constantly adjust in order to stay ahead of cyber attackers, stay exceptional knowledgeable on the most recent strategies assailants are utilizing to penetrate PC frameworks and on IT security. Experts look into new security innovation to choose what will most successfully ensure the safety of the company they work for. This may include going to cybersecurity meetings to hear first hand research from different experts who have encountered new sorts of assaults.
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.
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.
Centralized account management: Large ICS organizations require central authentication systems since managing each system is not possible. These organizations should enforce the below
Intrusion detection is the process of monitoring the events occurring in a computer system or network and analyzing them for signs of possible incidents, which are violations or imminent threats of violation of computer security policies, acceptable use policies, or standard security practices. Intrusion prevention is the process of performing intrusion detection and attempting to stop detected possible incidents. Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, attempting to stop them, and reporting them to security administrators. In addition, organizations use IDPSs for other purposes, such as identifying problems with security policies, documenting existing threats, and deterring individuals from violating security policies. IDPSs have become a necessary addition to the security infrastructure of nearly every organization. An IDS is composed of several components: Sensors which generate security events, a Console to monitor events and alerts and control the sensors, and a central Engine that records events logged by the sensors in a database and uses a system of rules to generate alerts from security events received. There are several ways to categorize an IDS depending on the type and location of the sensors and the methodology used by the engine to generate alerts. In many simple IDS implementations all three components are combined in a single device or appliance.
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.
Id cards are never a win, win situation. They are almost always lost, stolen, or broken, you name it they do it. ID cards should not be used as a main source of living in society and people should just go back to telling things verbally. ID cards can not benefit most people and should not be used.
