FIREWALL
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a private internal network and the public internet, preventing unauthorized access and protecting sensitive data from malicious threats.
A firewall can be a software application or a hardware device, and is commonly used in corporate and government networks to enhance security. Typically, firewalls analyze all network traffic, categorizing it into various types such as HTTP, FTP, SMTP, and others, and allow or block traffic based on the set rules. They can also filter data packets to ensure they conform with predefined standards, such as virus scanning, intrusion detection, and VPN support. Firewalls are essential components in any organization's security infrastructure to safeguard against cyber-attacks and ensure data confidentiality, integrity, and availability.
ENCRYPTION
There are different types of encryption techniques available, including symmetric encryption and asymmetric encryption, that use different methods to encode and decode the data.
Encryption is widely used in various applications, including online communication, financial transactions, and data storage, to ensure the confidentiality and integrity of sensitive and valuable information. It has become an essential tool to safeguard digital information from cyber threats and maintain the privacy rights of individuals and organizations.
DATA MASKING
Data masking is a technique used to protect sensitive information by replacing it with fictitious data.
This is usually done for non-production environments that are used for testing, development, or training. Data masking helps to maintain data privacy and security, while allowing for realistic testing and analysis without the risk of exposing sensitive information.
DATA ERASURE
Data erasure is the process of securely and permanently deleting all data from a storage device, such as a hard drive, solid-state drive, or USB flash drive.
This ensures that none of the data can be recovered or accessed by unauthorized parties. Data erasure is important when getting rid of old or unwanted devices, especially if they contain sensitive or confidential information.
DATA BACKUP
Data backup is the process of creating and storing copies of important files and information in a secure location, in case of unexpected data loss or corruption.
Backups can be done manually or automatically, and can be stored either on local storage devices such as external hard drives or cloud-based services.
Backups can prevent loss of valuable data due to hardware failures, natural disasters, cyber-attacks, or accidental deletions and ensure that data can be restored quickly.
