Network security is any activity designed to protect the usability and integrity of a network and data. It includes both hardware and software technologies. Importantly, Network securities target to curb many cyber threats arising as technology advances.

Core elements of a Network security

• People – Almost every cyberattack is targeted at people, even if the ostensible victim is a business or government institution. Hackers are invariably after private information about people or seeking to disrupt people’s lives. People thus need to be aware of their role in reducing and preventing threats.
• Processes – Organizations need to create policies and processes that reduce threats. They need to adapt to the shifting cybersecurity landscape. Regulations are part of this mix. Laws like GDPR and data breach notification statutes help protect people and businesses from cyberattacks.
• Technology – People and companies also need to invest in network security that protects them from cyberattacks.

The 3 Types of  Network Security

Network security entails a wide range of tools and techniques but it is mainly grouped into three categories:

• Data security – Hackers are often after accessing private data. Their reasons are different. In some cases, the hacker is simply stealing information like credit card numbers to sell on the black market. Other times, the information hacker wants to ruin the target by revealing private strategies. Data security involves protecting data from unauthorized access. It includes data encryption, data access control technologies and policies.
• Network security – In order for a cyberattack to occur,  the hacker must first find a way to gain access to the target’s network. Therefore, protecting networks is one of the most crucial thing of cyber security . Network security includes the following, firewalls, bastion hosts, appliance hardening, intrusion detection systems (IDS), security incident and event management (SIEM) systems etc.
• Application security – Hackers also like to access software applications like Enterprise Resource Planning (ERP), CRM, email servers and the like. Following app activities is a great way to spy on the target or disrupt its operations. Additionally,, Application security has many facets, but it usually combines policies (e.g. who is allowed to access the application and its administrative “back end”) and controls over the Application Programming Interfaces (APIs) that let other software programs gain access to the app.

Cyber threats to a network security

Cyber security threat is a malicious act that seeks to interfere with data, steal data, or disrupt IT functioning in general. The threats include computer viruses, data breaches, and Denial of Service  attacks. There are so many cyber threats out there today. The following are the most common threats:

• Malware/Ransomware

• Botnets
• Computer Viruses and Worms
• Phishing Attacks
• DDoS (Distributed Denial of Service)
•  Cryptojacking
• APT (Advanced Persistent Threats) Threats
• Trojan Horse
•  Rootkits
• SQL Injection Attack
