A non-physical threat is a potential cause of an incident that may result in;
- Loss or corruption of system data
- Disrupt business operations that rely on computer systems
- Loss of sensitive information
- Illegal monitoring of activities on computer systems
- Cyber Security Breaches
The non-physical threats are also known as logical threats. The following list is the common types of non-physical threats;
- Key loggers
- Denial of Service Attacks
- Distributed Denial of Service Attacks
- Unauthorized access to computer systems resources such as data
- Other Computer Security Risks
To protect computer systems from the above-mentioned threats, an organization must have logical security measures in place. The following list shows some of the possible measures that can be taken to protect cyber security threats
To protect against viruses, Trojans, worms, etc. an organization can use anti-virus software. In additional to the anti-virus software, an organization can also have control measures on the usage of external storage devices and visiting the website that is most likely to download unauthorized programs onto the user’s computer.
Unauthorized access to computer system resources can be prevented by the use of authentication methods. The authentication methods can be, in the form of user ids and strong passwords, smart cards or biometric, etc.
Intrusion-detection/prevention systems can be used to protect against denial of service attacks.There are other measures too that can be put in place to avoid denial of service attacks.
- A threat is any activity that can lead to data loss/corruption through to disruption of normal business operations.
- There are physical and non-physical threats
- Physical threats cause damage to computer systems hardware and infrastructure. Examples include theft, vandalism through to natural disasters.
- Non-physical threats target the software and data on the computer systems.
