Digital or computer forensics focuses on the digital domain including computer forensics, network forensics, and mobile forensics. As the cyber security profession evolves, organizations are learning the importance of employing digital forensic practices into their everyday activities. Computer forensic practices can help investigate attacks, system anomalies, or even help System administrators detect a problem by defining what is normal functional specifications and validating system information for irregular behaviors. In the event of a cyber attack or incident, it is critical investigations be carried out in a manner that is forensically sound to preserve evidence in the event of a breach of the law. Far too many cyber attacks are occurring across the globe where laws are clearly broken and due to improper or non existent forensic investigations, the cyber criminals go either unidentified, undetected, or are simply not prosecuted. Cyber Security professionals who acquire a firm grasp on the principles of digital forensics can become invaluable members of Incident Handling and Incident response teams. The Computer Hacking Forensic Investigator course provides a strong baseline knowledge of key concepts and practices in the digital forensic domains relevant to todays organizations. CHFI provides its attendees a firm grasp on the domains of digital forensics. Who Is It For The CHFI program is designed for all IT professionals involved with information system security, computer forensics, and incident response. Target Audience. Police and other law enforcement personnel. Defense and Military personnele Business Security professionals. Systems administrators. Legal professionals. Banking, Insurance and other professionals. Government agencies. Computer security Wikipedia. Computer security, also known as cyber security or IT security, is the protection of computer systems from the theft and damage to their hardware, software or information, as well as from disruption or misdirection of the services they provide. Cyber security includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection. Also, due to malpractice by operators, whether intentional, accidental, IT security is susceptible to being tricked into deviating from secure procedures through various methods. The field is of growing importance due to the increasing reliance on computer systems and the Internet,4wireless networks such as Bluetooth and Wi Fi, the growth of smart devices, including smartphones, televisions and tiny devices as part of the Internet of Things. Vulnerabilities and attackseditA vulnerability is a weakness in design, implementation, operation or internal control. Most of the vulnerabilities that have been discovered are documented in the Common Vulnerabilities and Exposures CVE database. An exploitable vulnerability is one for which at least one working attack or exploit exists. Vulnerabilities are often hunted or exploited with the aid of automated tools. To secure a computer system, it is important to understand the attacks that can be made against it, and these threats can typically be classified into one of the categories below BackdooreditA backdoor in a computer system, a cryptosystem or an algorithm, is any secret method of bypassing normal authentication or security controls. They may exist for a number of reasons, including by original design or from poor configuration. They may have been added by an authorized party to allow some legitimate access, or by an attacker for malicious reasons but regardless of the motives for their existence, they create a vulnerability. Denial of service attackeditDenial of service attacks Do. S are designed to make a machine or network resource unavailable to its intended users. Attackers can deny service to individual victims, such as by deliberately entering a wrong password enough consecutive times to cause the victim account to be locked, or they may overload the capabilities of a machine or network and block all users at once. While a network attack from a single IP address can be blocked by adding a new firewall rule, many forms of Distributed denial of service DDo. S attacks are possible, where the attack comes from a large number of points and defending is much more difficult. Such attacks can originate from the zombie computers of a botnet, but a range of other techniques are possible including reflection and amplification attacks, where innocent systems are fooled into sending traffic to the victim. Direct access attackseditAn unauthorized user gaining physical access to a computer is most likely able to directly copy data from it. They may also compromise security by making operating system modifications, installing software worms, keyloggers, covert listening devices or using wireless mice. Even when the system is protected by standard security measures, these may be able to be by passed by booting another operating system or tool from a CD ROM or other bootable media. Disk encryption and Trusted Platform Module are designed to prevent these attacks. Install Old Version Of Rubygems. EavesdroppingeditEavesdropping is the act of surreptitiously listening to a private conversation, typically between hosts on a network. For instance, programs such as Carnivore and Narus. In. Sight have been used by the FBI and NSA to eavesdrop on the systems of internet service providers. Even machines that operate as a closed system i. Hacking Definition Hacking is unauthorized intrusion into a computer or a network. The person engaged in hacking activities is generally referred to. TEMPEST is a specification by the NSA referring to these attacks. SpoofingeditSpoofing is the act of masquerading as a valid entity through falsification of data such as an IP address or username, in order to gain access to information or resources that one is otherwise unauthorized to obtain. There are several types of spoofing, including TamperingeditTampering describes a malicious modification of products. So called Evil Maid attacks and security services planting of surveillance capability into routers1. Privilege escalationeditPrivilege escalation describes a situation where an attacker with some level of restricted access is able to, without authorization, elevate their privileges or access level. For example, a standard computer user may be able to fool the system into giving them access to restricted data or even to become root and have full unrestricted access to a system. PhishingeditPhishing is the attempt to acquire sensitive information such as usernames, passwords, and credit card details directly from users. Phishing is typically carried out by email spoofing or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Preying on a victims trust, phishing can be classified as a form of social engineering. ClickjackingeditClickjacking, also known as UI redress attack or User Interface redress attack, is a malicious technique in which an attacker tricks a user into clicking on a button or link on another webpage while the user intended to click on the top level page. This is done using multiple transparent or opaque layers. The attacker is basically hijacking the clicks meant for the top level page and routing them to some other irrelevant page, most likely owned by someone else. A similar technique can be used to hijack keystrokes. Carefully drafting a combination of stylesheets, iframes, buttons and text boxes, a user can be led into believing that they are typing the password or other information on some authentic webpage while it is being channeled into an invisible frame controlled by the attacker. Social engineeringeditSocial engineering aims to convince a user to disclose secrets such as passwords, card numbers, etc. A common scam involves fake CEO emails sent to accounting and finance departments. In early 2. 01. 6, the FBI reported that the scam has cost US businesses more than 2bn in about two years. In May 2. 01. 6, the Milwaukee Bucks. NBA team was the victim of this type of cyber scam with a perpetrator impersonating the teams president Peter Feigin, resulting in the handover of all the teams employees 2. W 2 tax forms. 1.

Cultural concepts can help different segments of the organization work effectively or work against effectiveness towards information security within an organization. Exploring the Relationship between Organizational Culture and Information Security Culture provides the following definition of information security culture ISC is the totality of patterns of behavior in an organization that contribute to the protection of information of all kinds.
