Common Cyber Security Technologies and Their Functions

In today’s digital age, where cyber threats are becoming increasingly sophisticated, cyber security technologies play a crucial role in safeguarding our sensitive information. By using cutting-edge technologies and advanced techniques, these tools are designed to detect, prevent, and respond to cyber attacks, ensuring the confidentiality, integrity, and availability of data. Let’s explore some common cyber security technologies and their functions.

1.Firewall: A firewall acts as a barrier between an internal network and the external internet, monitoring and controlling incoming and outgoing network traffic. It examines each data packet, determines if it meets certain security criteria, and allows or blocks it accordingly.

2.Intrusion Detection System (IDS): An IDS monitors network traffic for suspicious activities and alerts administrators when potential threats are detected. It analyzes patterns, signatures, and anomalies to identify malicious behavior and helps in early detection and prevention of cyber attacks.

3.Antivirus Software: Antivirus software scans files, programs, and emails for known malware and viruses. It detects and removes or quarantines malicious code, preventing it from spreading and causing harm to the system.

4.Encryption: Encryption is the process of converting sensitive information into an unreadable format, known as ciphertext, to protect it from unauthorized access. It ensures that only authorized parties can decrypt and access the information.

5.Virtual Private Network (VPN): A VPN creates a secure, encrypted connection over a public network, such as the internet. It allows users to transmit data securely and privately, protecting their online activities from eavesdropping and unauthorized access.

6.Two-Factor Authentication (2FA): 2FA adds an extra layer of security by requiring users to provide two different types of authentication factors, such as a password and a unique code sent to their mobile device. This reduces the risk of unauthorized access even if the password is compromised.

7.Security Information and Event Management (SIEM): SIEM tools collect and analyze security event logs from various sources to detect and respond to security incidents. They provide real-time monitoring, log correlation, and threat intelligence, helping organizations identify and mitigate potential cyber threats.

8.Intrusion Prevention System (IPS): An IPS works in conjunction with a firewall and IDS to actively block and prevent malicious activities. It analyzes incoming and outgoing network traffic, identifies potential threats, and takes immediate action to stop them.

Additional essential skills for work, including:

• Understanding and complying with your employer’s IT and social

media policies

• Complying with security policies when working remotely 
• Using digital collaboration tools to meet, share information, and
collaborate with colleagues (A good example is using Google Docs
to collaborate on a document. 
Given the rapid digitization of work, I’d also argue that basic digital literacy now goes beyond turning on devices, using technology to communicate, and the like. So, to the above lists, I would also add the following
as essential basic skills that we all need:

• Having a positive attitude to new technologies and not shying away

from using new tools. This includes seeing the value of technology,

and how it can help businesses and individuals succeed.

• Generally being tech savvy, by which I mean being aware of new

technologies that are emerging and considering how those technologies might impact your job.

• Understanding the potential pitfalls of technology. A good example
is the “filter bubble” phenomenon. 

Here, search and social media platforms serve up personalized content based on what they know about you and your previous activity online, potentially creating a
