Fundamentals of Information Systems SecurityInformation Security and Risk Management. IntroductioneditInformation security means protecting information data and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. Information Security management is a process of defining the security controls in order to protect the information assets. Security ProgrameditThe first action of a management program to implement information security is to have a security program in place. Though some argue the first act would be to gain some real proof of concept and explainable thru display on the monitor screen security knowledge.

Security ControlseditSecurity Controls can be classified into three categories. Administrative Controls which include. Developing and publishing of policies, standards, procedures, and guidelines. Screening of personnel. Conducting security awareness training and. Implementing change control procedures. Technical or Logical Controls which include. Implementing and maintaining access control mechanisms. Password and resource management. Identification and authentication methods. Security devices and. Configuration of the infrastructure. Physical Controls which include. Controlling individual access into the facility and different departments. Locking systems and removing unnecessary floppy or CD ROM drives. Protecting the perimeter of the facility. Monitoring for intrusion and. Environmental controls. Security Note It is the responsibility of the information owner usually a Sr. The Elements of SecurityeditVulnerability. It is a software, hardware, or procedural weakness that may provide an attacker the open door he is looking for to enter a computer or network and have unauthorized access to resources within the environment. Sonicwall Vpn Client Linux on this page. Vulnerability characterizes the absence or weakness of a safeguard that could be exploited. E. g. a service running on a server, unpatched applications or operating system software, unrestricted modem dial in access, an open port on a firewall, lack of physical security etc. Threat. Any potential danger to information or systems. A threat is a possibility that someone person, sw would identify and exploit the vulnerability. The entity that takes advantage of vulnerability is referred to as a threat agent. E. g. A threat agent could be an intruder accessing the network through a port on the firewall. Risk. Risk is the likelihood of a threat agent taking advantage of vulnerability and the corresponding business impact. Reducing vulnerability andor threat reduces the risk. E. g. If a firewall has several ports open, there is a higher likelihood that an intruder will use one to access the network in an unauthorized method. Exposure. An exposure is an instance of being exposed to losses from a threat agent. Vulnerability exposes an organization to possible damages. E. g. If password management is weak and password rules are not enforced, the company is exposed to the possibility of having users passwords captured and used in an unauthorized manner. Countermeasure or Safeguard. It is an application or a sw configuration or hw or a procedure that mitigates the risk. E. g. strong password management, a security guard, access control mechanisms within an operating system, the implementation of basic inputoutput system BIOS passwords, and security awareness training. The Relation Between the Security Elements. Example If a company has antivirus software but does not keep the virus signatures up to date, this is vulnerability. The company is vulnerable to virus attacks. The threat is that a virus will show up in the environment and disrupt productivity. The likelihood of a virus showing up in the environment and causing damage is the risk. If a virus infiltrates the companys environment, then vulnerability has been exploited and the company is exposed to loss. The countermeasures in this situation are to update the signatures and install the antivirus software on all computers. Threat Agent gives rise to Threat exploits Vulnerability leads to Risk. Assets and causes an Exposure can be counter measured by Safeguard. Threat Agent. Alternative Description A threat agent causes the realisation of a threat by exploiting a vulnerability. The measurement of the extent that this exploitation causes damage is the exposure. The organisational loss created within the exposure is the impact. Risk is the probability that a threat event will generate loss and be realised within the organisation. Example Target A bank contains money. Threat There are individuals who want, or need, additional money. Vulnerability The bank uses software that has a security flaw. Exposure 2. 0 of the banks assets are affected by this flaw. Exploit By running a small snippet of code malware, the software can be accessed illegally. Threat Agent There are hackers who have learned how to use this malware to control the banks software.
