What's The Difference Between IDS And IBS?

IDS and IPS are both network security technologies that are used to protect computer networks from security threats. IDS stands for Intrusion Detection System, while IBS stands for Intrusion Prevention System. The main difference between the two is in the way they handle detected security threats.
An IDS is a passive system that monitors network traffic and logs suspicious activity. When an IDS detects a potential security threat, it sends an alert to the network administrator who can then take action to investigate and mitigate the threat. The primary function of an IDS is to detect and alert administrators of potential attacks, but it does not take any actions to stop or prevent the attack from happening.
On the other hand, an IPS is an active system that not only detects security threats but also takes immediate action to prevent them. When an IPS detects a security threat, it can automatically block traffic from the source of the threat or take other measures to prevent the attack from succeeding. IPS technology is more advanced than IDS technology, and it is considered to be a more proactive approach to network security.
In summary, an IDS is a passive system that only detects and alerts administrators of potential threats, while an IPS is an active system that not only detects but also takes actions to prevent security threats from happening.
How Is Ransomware Encryption Different From Hacking?

Ransom encryption, also known as ransomware, is a type of malicious software that encrypts the victim's files and demands a ransom payment in exchange for the decryption key. Ransomware attacks are a form of cyber extortion and are considered a criminal act.
Hacking, on the other hand, is the unauthorised access or manipulation of computer systems or networks by individuals with malicious intent. Hacking can involve breaking through security measures, stealing data, or causing damage to systems or networks.
While ransomware attacks involve encryption of data, they are distinct from hacking in that they rely on social engineering techniques such as phishing emails or exploiting vulnerabilities in software to gain access to a victim's system. Ransomware attackers do not typically seek to steal data or cause damage to the system, but instead use encryption as a means of extorting money from the victim.
In summary, ransom encryption, or ransomware, is a form of cyber extortion that involves the encryption of a victim's data, while hacking involves unauthorised access or manipulation of computer systems or networks. While both are forms of cyberattacks, they differ in their goals and methods.
What Is Firewall And Why It Is Used?

A firewall is a security system that is used to control and filter the traffic that passes between a computer network and the internet. It acts as a barrier between the internal network and external networks such as the internet.
Firewalls are used to protect computer networks from unauthorized access and malicious attacks by examining incoming and outgoing traffic and blocking any traffic that does not meet specific security criteria. They can be configured to allow or block traffic based on various factors such as source and destination IP addresses, ports, protocols, and content.
Firewalls can be hardware-based, software-based, or a combination of both. Hardware firewalls are physical devices that are installed between the network and the internet, while software firewalls are programs that run on individual computers or servers.
Firewalls are essential for protecting computer networks from cyber threats such as hacking, malware, and viruses. They are used in both small and large organizations, as well as in personal computers and home networks, to ensure the security and privacy of sensitive data and information.
What Steps Will You Take To Secure Server?

Use strong passwords: Ensure that all user accounts, especially administrative accounts, have strong passwords that are difficult to guess or crack.
Restrict access: Limit server access only to authorized personnel, and grant access based on the principle of least privilege.
Use encryption: Encrypt sensitive data both in transit and at rest, using technologies such as SSL/TLS and full-disk encryption.
Enable a firewall: Use a firewall to filter traffic to and from the server, and only allow traffic that is necessary for the server's operation.
Monitor the server: Implement monitoring tools to detect and alert of any suspicious activity or attempted attacks.
Implement intrusion detection and prevention: Use intrusion detection and prevention systems to help prevent unauthorized access and protect the server from malicious activity.
Regularly backup data: Create and regularly test backups of critical data and store them in a secure location to protect against data loss in case of a security breach or other incident.
Implement access controls: Implement role-based access controls (RBAC) to ensure that users only have access to resources they require for their work.
Regularly audit server security: Perform regular security audits of the server to identify and address any vulnerabilities and ensure that all security measures are up-to-date and functioning properly.
These are just some of the steps that can be taken to secure a server, and the specific security measures will depend on the individual needs of the organization and the server's function.

What Is Cyber Crime And Cyber Security?

Cybercrime refers to criminal activities that are carried out using the internet or other computer networks. These crimes can range from simple phishing scams and identity theft to more complex crimes such as hacking, cyber espionage, and cyber terrorism.
Cybersecurity, on the other hand, is the practice of protecting computer systems and networks from cyber threats, attacks, and unauthorised access. It involves implementing various security measures and technologies such as firewalls, encryption, antivirus software, and intrusion detection systems to safeguard data, information, and systems.
Cybercrime and cybersecurity are closely related as cybercrime poses a significant threat to cybersecurity. As cybercriminals continue to develop new methods and techniques for carrying out cyber attacks, cybersecurity professionals must continually update and improve their defenses to stay ahead of the threats.
