Cybersecurity is a protection of internet connected systems. It also includes hardware, software, and data from cyber attacks. In computers, security comprises cybersecurity and physical security they both are used by the companies to protect the system against unauthorized access to the data centers and other computerized systems. The information security is designed to maintain the confidentiality, integrity, and availability of the data is a subset of cybersecurity.
Elements of the cybersecurity
- Application security.
- Information security.
- Network security.
- Disaster recovery.
- Business continuity planning.
- Operational security.
- End-user education.
One of the most problematic elements of cybersecurity is the constantly evolving nature of security risks. The traditional approach has been to focus resources on crucial system components and protect against the biggest known threats, which meant leaving components undefended and not protecting systems against less dangerous risks. To deal with the current environment, advisory organizations are promoting a more proactive and adaptive approach. The National Institute of Standards and Technology (NIST), for example, recently issued updated guidelines in its risk assessment framework that recommend a shift toward continuous monitoring and real-time assessments.
Types of cyber threats
- Ransomware is a type of malware that involves an attacker locking the victim’s computer system files — typically through encryption — and demanding a payment to decrypt and unlock them.
- Malware is any file or program used to harm a computer user, such as worms, computer viruses, Trojan horses and spyware.
- Social engineering is an attack that relies on human interaction to trick users into breaking security procedures in order to gain sensitive information that is typically protected.
- Phishing is a form of fraud where fraudulent emails are sent that resemble emails from reputable sources; however, the intention of these emails is to steal sensitive data, such as credit card or login information.
The use of cyber security can help prevent cyber attacks, data breaches, and identity theft and can aid in risk management. When an organization has a strong sense of network security and an effective incident response plan, it is better able to prevent and mitigate these attacks. For example, end user protection defends information and guards against loss or theft while also scanning computers for malicious code. As the cyber threat landscape continues to grow and emerging threats, such as the internet of things, require hardware and software skills, it is estimated that there are 1 million unfilled cybersecurity jobs worldwide.
