Cyber Security Info

What is the internet?

This is a worldwide system of interconnected computers where users can gain information from, provided they have the prerequisite access rights. The internet is made up of the hardware devices- computers, mobile phones and other devices with access to the internet- and the network protocols in force including the transmission control protocol also called the internet protocol. The beauty of the internet is that even if the hardware in any section of the world is destroyed, users form other parts of the world have unlimited access to the internet.


What is cyber security?

These are processes and measures put in place to protect devices, systems, networks, data and programs from attack, unauthorised access or destruction. It involves the use of different strategies, software and hardware components to prevent attack or unauthorised access to information, devices or other internet related items. Cyber security may also be used to refer to different measures taken to enhance the security, anonymity- where applicable, and privacy of the users of different devices and systems. To discover the vulnerabilities in any systems, the crest penetration testing can be done to all systems and devices.

What types of cyber security is there?

There are different ways to classify cyber security. However, we take a look at a five part cyber security classification that includes: network security, critical infrastructure security, application security, cloud security and the Internet of things security. Critical Infrastructure Security consists of measures to secure the most basic infrastructure in society including power grids and infrastructure, water purification systems, hospitals, traffic lights and even shopping centres.


Network security protects different networks from attacks and unauthorised access while application security involves the protection of applications during their development stages against attacks by utilising both software and hardware security measures. Cloud security on the other hand prevents unauthorised access of information uploaded in different cloud computing resources. Lastly, the internet of things security protects both critical and non-critical systems including routers, sensors, appliances, cameras and printers against attack.


Why is cyber security important?

Different organisations receive, collect and process a lot of private information about clients or the citizens. Some of the information, in the wrong hands, could be used to perpetuate illegal activities including identity theft, Ponzi schemes and so on. Cyber security ensures that all the information shared remains confidential and inaccessible to unauthorised individuals.


Businesses may also transmit sensitive information to their vendors, partners or even to the government including their financial records and books of accounts, patents and intellectual property, security information and so on. Exposure of these may amount to exposure of trade secrets which would be detrimental to the business community. Cyber security ensures that the forces of demand and supply are not altered by exposure of sensitive information and therefore free market regulation stays in force.


For the government, exposure of security information, details of government informants, war strategies, if any, information on military personnel and their families or even the perpetrators of heinous crimes against humanity, intelligence assets and strategies could have catastrophic and irreparable damage to a nation. Cyber security ensures that the government can retain top secrecy on such information and function properly.


As an organisation, government or individual, it is paramount to uncover the vulnerabilities in the systems and devices under your care by carrying out testing such as the crest penetration testing. These tests should be carried out on a regular basis given the speed with which phishers and attackers are fine tuning their attack strategies.
