Encryption
Encryption is another important tool in protecting sensitive data. It involves converting plain text into a code or cipher that someone with the decryption key can only read. This ensures that even if hackers can access the data, they cannot read it without the key. Encryption can be applied to data at rest, such as stored on a hard drive, or in transit, such as when transmitted over the internet. It is significant to use strong encryption algorithms and to keep the decryption keys secure to ensure the effectiveness of this safeguard.
Firewalls
Firewalls are a network security system that looks after and handles incoming and outgoing network traffic. It is a barrier between a reliable internal network and unreliable external networks like the internet. Firewalls can be hardware, software, or an amalgamation of both. They use a set of rules to determine which traffic is permitted to pass through and which traffic should be blocked. This helps prevent unauthorized access to the network and the spread of malware or other malicious activity. Firewalls can also be configured to log and alert on suspicious activity, providing an additional layer of security.
Antivirus Software
Antivirus software is a program designed to detect, prevent, and eliminate malicious software, also known as malware. Malware can include viruses, worms, Trojans, spyware, and other categories of harmful software that can cause damage to a computer system or steal sensitive information. Antivirus software typically scans files and programs on a computer system for known malicious code patterns. If a file or program is found to contain malware, the antivirus software will either quarantine or delete the file or attempt to remove the malicious code.
In addition to real-time scanning, many antivirus programs offer features such as email scanning, web protection, and automatic updates to ensure the software is up-to-date with the latest malware definitions.
Antivirus software is an important part of maintaining the security of a computer system, as it can help prevent malware infections and protect sensitive information from being stolen or compromised.
Backups
Backing up your important data is crucial to confirm you don’t lose it in case of a system failure or a malware attack.
