These rules should cover topics including password management, access controls, incident reporting, and data handling. To adapt to evolving threats, regular review and updates are required.
• Access control measures:
It is critical to control access to sensitive data and systems in order to prevent unwanted access. Implementing strong authentication mechanisms such as multi-factor authentication and limiting privileges based on role.
• Network Security:
Network security is used to secure your web based traffic, online data, information or digital systems. It basically focuses on protecting the infrastructure and data transmitted over networks.
There are below components contributes in network security:-
1. Firewall :
Firewalls act as a barrier between internal and external networks which used for inspecting and filtering incoming and outgoing traffic. It comes in hardware and software that deny all unwanted traffic until and unless you have a policy to allow it.
2. Intrusion detection systems (IDS) :
Intrusion detection systems (IDS) monitor network traffic for suspicious activities, alerting administrators to potential threats. IDS is passive monitoring solution for detecting a cybersecurity threats to an organization. If a potential intrusion is detected, the IDS generates an alerts that notifies security to investigate the incident and take immediate action on that.
3. Intrusion prevention systems (IPS) :
IPS is used to take an action to block any types of threats to protect systems or network from unknown viruses or vulnerabilities. IPS solutions used to detect also actively block and prevent potential threats from entering a network. By monitoring network traffic in real-time, IPS solutions provide an additional layer of security.
4. Virtual private networks (VPN) :
VPN is technology used to connect securely two or more networks remotely over the internet. VPNs allow secure remote access to private networks over the internet. By encrypting data transmitted between a user and the network, VPNs ensure confidentiality and integrity.
5. Endpoint Security :
Endpoints devices such as computers, laptops and mobile devices, represent potential entry points for cyber threats. Protecting these endpoints is important for overall cybersecurity.
6. Anti-malware solutions :
Installing and upgrading anti-malware software on a regular basis helps in the detection and removal of harmful software from endpoints. These solutions provide protection against viruses, spyware, and other forms of malware.
Requirement to protect from Viruses
• Regular software updates :
Regularly updating software and applying accurate patches is important for vulnerabilities. Outdated software can become an easy to target for attackers.
