What is cybersecurity?
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyber attacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes. The typical types of cybersecurity threats including ransomware, malware, social engineering, and phishing. Thus, the cybersecurity experts are needed to help provide protection of computer systems from these kinds of thefts or damages to their client’s hardware, software or data.
Why cybersecurity is increasingly important?
The cybersecurity field is growing its importance because of the increasing reliance on computer systems, the internet, wireless networks as well the electronic devices such as mobile phones. However, implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.
How to solve cybersecurity issues?
In computer security, a countermeasure could be an action, device, procedure or technique that can help to reduce a threat, a vulnerability or an attack by eliminating or preventing cyber risks, reducing the potential harm it could bring. For example, it could be helpful to establish IT security architecture by designing artifacts that describe how the security controls are positioned in the cybersecurity framework and how they relate to the overall information technology architect. Also, security measures such as user account access controls, firewalls, intrusion detection system, vulnerability management can all brings a certain level of cyber protection for companies. Taking the firewall as an example, a firewall can function as a protective umbrella to prevent organizations from digital attacks. Firewall which can be either hardware or software is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. Moreover, it is necessary for companies to build cyber incident response teams in organizations who are responsible for providing a cyber incident response in a timely manner.
