Cybersecurity

Cybersecurity is the protection of systems, programs, and networks from digital attacks. This practice is used both by individuals and businesses to prevent unauthorised access to data centres and other computer systems.
An effective cybersecurity plan can provide a good security posture against hostile assaults intended to gain access, change, delete, destroy, or extort sensitive data and systems belonging to a business or user. Cybersecurity is also a tool used for preventing attacks that aim to disable or disrupt the operation of a system or device. 

Why do we need cybersecurity?

Cybersecurity is important because it covers everything related to protecting our data from being stolen and used to cause harm. This can be sensitive data, intellectual property, industry, government information, etc. It is crucial to have advanced cyber protection programs to secure this data. People rely on infrastructures like hospitals and other healthcare institutions, powerplants and financial service programs. We need these to keep our society running.
At an individual level, digital attacks can result in attempts of extortion or identity theft, which can do serious damage to that person’s life. 

What does cybersecurity entail?

A successful cybersecurity strategy has many layers of protection spread across the computers, programs, networks, or data that it aims to keep safe. In an organisation, three main elements must complement each other to create an effective defence against cyberattacks. These elements are people, processes, and technology.

  • People. Users must be aware of and adhere to basic data security principles, such as choosing strong passwords, being cautious when opening attachments in emails, and regularly backing up their data. 
  • Processes. Organisations must have a strategy for dealing with both attempted and successful cyberattacks. A good strategy should include identifying attacks, detecting, and responding to threats, and recovering from digital attacks. 
  • Technology. Technology is essential for providing individuals and organisations with the tools required to protect themselves from cyberattacks. These are the main entities that must be protected: computers, networks, and the cloud. For their protection one can use DNS filtering, antivirus software, etc. 

Types of cybersecurity threats

Attackers are always looking for new ways to evade defensive measures and make use of weaknesses. The latest cybersecurity threats take advantage of remote working environments, new cloud services and remote access tools. These evolving threats include: 

  • Malware. It is a type of software created to provide unauthorised access or cause damage to computers. Malware attacks are designed to get around detection methods and include viruses, Trojans, and spyware. 
  • Ransomware. It is a type of malware that blocks access to files, data or systems and threatens to destroy or leak the data until the ransom is paid. However, paying the ransom is not a guarantee that the files will not be leaked or destroyed. 
  • Phishing. It is a type of cyberattack that resembles emails from reputable sources and tricks users into providing their sensitive information. The goal is to steal data like credit card numbers or login information. It is the most common type of cyberattack.

4 main advantages of cybersecurity

  • Protection against internal threats. In the cybersecurity chain, the weakest link is the human factor. Insider threats can come from trusted partners, former or even current employees. Moreover, the growth of remote working made it easier for such threats to stay unnoticed until it is too late. 
  • Protection against external threats. The primary goal of external cyberattacks is financial gain; however, the reasons behind them can vary. A strong cybersecurity posture can help an organisation to detect and respond to the devices, methods and entry points being used. 
  • Cost savings and value. It is crucial to compare the cost of dealing with one cyberattack and the value of taking preventative measures. It is cost-efficient to keep existing customers satisfied by preparing the business for responding and recovering after the digital attack. 
  • Improved productivity. Successful cyberattacks can slow down personal devise and networks, making it impossible for websites to function or for employees to work. By using a range of cybersecurity measures you can prevent cyberattacks or reduce the recovery time, which can improve productivity.
