    What Computer Skills are needed for Cyber Security?

    As the security of online data becomes an increasing concern for organizations, the importance of cyber security experts has grown, and with it, the need for specific skills. To be a cyber security expert, one needs a wide range of computer skills to adequately protect an organization’s systems. This article will outline and explain some of the essential computer skills required for cyber security professionals.

    Networking and System Administration

    Networking and system administration skills are crucial for any cyber security expert. These skills allow a professional to manage and monitor an organization’s computer systems and networks. Some of the essential networking and system administration skills for cyber security experts include configuring and maintaining firewalls and intrusion detection systems, understanding the TCP/IP protocol, and managing switches and routers.

    For cyber security experts to be successful in their work, they must be able to monitor network activity and recognize anomalies or patterns that suggest a cyber attack may be happening. In addition, they must have the ability to address network-related issues and ensure that they are resolved promptly.

    Operating Systems and Virtual Machines

    Knowledge of Operating Systems (OS) is an essential skill for cyber security experts. They must be familiar with different operating systems such as Windows, macOS, and Linux to understand how they function and how they are used in an organization.

    Cyber security experts must also have knowledge of virtual machines, which is a software program that simulates a computer system, allowing multiple operating systems to run on a single physical computer. This skill is essential in testing software for security vulnerabilities and creating sandbox environments for testing malware.

    Network Security Control

    Network Security Control is another critical area of cyber security. This includes knowledge of access controls such as firewalls, authentication, intrusion detection, and identification systems, and encryption techniques. Without these skills, cyber security experts will not be able to protect an organization’s network from cyber threats effectively.

    Some critical network security control skills include configuring and managing firewalls, VPN, DNS, VLAN, and other network protocols. Cyber security experts must be able to detect and respond to security incidents, which includes monitoring and investigating network incidents and taking appropriate actions to address them.

    Coding for Cyber Security

    While cyber security may not necessarily require extensive programming knowledge, a basic understanding of at least one or two programming languages is essential. A cyber security expert should have the ability to write and understand code and be familiar with different programming languages such as Python, Java, and C++. Familiarity with programming is essential for testing, reverse engineering malware, and exploiting vulnerabilities.

    Cyber security experts with programming knowledge can develop tools and scripts to automate tasks such as scanning and penetration testing. This will help to detect vulnerabilities and identify risks quickly, saving time and improving the efficiency of security operations.

    Cloud Security and its importance in Cyber Security

    Cloud computing helps organizations reduce costs and improve the efficiency of their operations. However, it also introduces new security risks that must be addressed by cyber security experts. One such risk is unauthorized access to data or applications stored in the cloud.

    Cyber security experts should be familiar with the cloud service models such as IaaS (Infrastructure as a Service), SaaS (Software as a Service), and PaaS (Platform as a Service). They should also be able to implement security controls such as access controls, encryption, and identity and access management.

    Blockchain Security and its implications for Cyber Security

    Blockchain technology is becoming increasingly prevalent in various industries, including finance, healthcare, and supply chain. The decentralized and secure nature of blockchain makes it an attractive option to various organizations.

    Understanding blockchain technology is a critical skill for cyber security experts. They should be able to design, implement and secure blockchain-based solutions, and have the ability to detect and respond to blockchain-related threats and vulnerabilities. This also includes knowledge of smart contracts and distributed ledger technologies.

    Challenges of securing the Internet of Things (IoT)

    The Internet of Things (IoT) is a network of interconnected devices that communicate with each other through the internet. While IoT devices offer many benefits, they also pose significant challenges for cyber security experts.

    One of the challenges is the lack of regulation and standardization, which makes it difficult to secure IoT devices. Another challenge is the huge number of IoT devices, making it impossible to protect and monitor every device.

    To secure the IoT, cyber security experts need to be familiar with different technologies and approaches to securing IoT devices such as encryption, secure firmware updates, and secure communication channels.

    Cyber Security and the absence of Artificial Intelligence (AI)

    Artificial Intelligence (AI) is a technology that can help organizations detect and respond to cyber threats quickly. AI can be used to analyze vast amounts of data in real-time, identify patterns, and predict attacks. However, AI cannot replace human intelligence in cyber security.

    Cyber security experts must have the ability to analyze data, identify patterns, and recognize anomalous behavior that may indicate a cyber attack. They must also have the ability to respond appropriately and take action to protect the organization’s systems and data.

    In conclusion, cyber security experts require a wide range of computer skills to deal with the ever-increasing number and complexity of cyber threats. These skills include networking and system administration, knowledge of operating systems and virtual machines, network security control, coding, cloud security, blockchain security, IoT security, and the ability to conduct effective analysis and response to cyber threats.
