The paper concludes with some comments directed towards the definition of artificially "alive" systems and experimentation. It then examines how viruses meet properties associated with life as defined by some researchers in the area of artificial life and self- organizing systems. This paper begins with a description of how computer viruses operate and their history, and of the various ways computer viruses are structured. Simply b ecause computer viruses do not exist as organic molecules may not be sufficient reason to dismiss the classification of this form of "vandalware" as a form of life. However, only recently have some scientists begun to ask if computer viruses are not a form of artificial life - a self-replicating organism. Viruses have been written about as a security problem, as a social problem, and as a possible means of performing useful tasks in a distributed computing environment. There has been considerable interest in computer viruses since they first appeared in 1981, and especially in the past few years as they have reached epidemic numbers in many per- sonal computer environments. A proposed aviation CSIRT requires the adoption of best practice cyber security incident response standards as a practical solution to manage aviation cyberattacks. Since the aviation sector is complex to manage, there is a need to establish an integrated CSIRT approach that include stakeholders within the ecosystem. To achieve such a framework, globally established CSIRTs are reviewed. An aviation CSIRT should implement frameworks, programs and international information security standards, and aviation communities need to share cyber information with the CSIRT. Acknowledging the urgency and importance of protecting civil aviation’s critical infrastructure, information and communication technology systems and data against cyber threats this research identifies that there is a need for a CSIRT framework for the Sub-Saharan aviation community. The aviation community is mandated to sustain safety and security of operations and passengers in Southern Africa. No mention of a transport or critical infrastructure sector CSIRT, under which an aviation CSIRT can report aviation sector cyber-attacks is made. The South African Cybersecurity Hub (SACH) acts as a national point of contact for the coordination of cybersecurity incidents in South Africa, but to date has only been successful in assisting with the establishment of a finance sector CSIRT. This paper reviews the various virus and antivirus patters and various detection schemes.Ĭomputer Security Incident Response Teams (CSIRTs) provide information security incident response services to communities. To stay current, they must be developers of these antiviruses update their databases whenever new viral strains arise. Antiviruses therefore scan the computer using some specific patterns of bytes indicative of known viruses. Antiviruses on the other hand are programs specially developed to counter challenges brought about by viruses as they protect the computer systems from virus attacks by heavily relaying on the controls enhanced in their databases. Viruses are represented as patterns of computer instructional codes that exist over time in computer systems. Abstract-Computer viruses are executable code programs that have a unique ability to replicate themselves in computer system and spread rapidly from one computer to another affecting file, documents and programs to alter their normal running.
