FAQ’s

An Intrusion Detection System (IDS) monitors network traffic for suspicious activities and sends alerts to administrators when a potential threat is detected, but it does not take any direct action to stop the threat. On the other hand, an Intrusion Prevention System (IPS) not only detects suspicious activities but also actively blocks or prevents malicious traffic from reaching the system. Essentially, IDS is passive and serves as a monitoring tool, while IPS is proactive and works as a protective barrier.

Encryption is a security technique that transforms data into unreadable code, ensuring that only authorized users with the correct key can decrypt and access the original information. It is a defensive mechanism used to protect sensitive information from unauthorized access. In contrast, hacking is an offensive act where an individual or group tries to exploit vulnerabilities in systems or networks to gain unauthorized access, steal data, or disrupt services. While encryption is about safeguarding data, hacking attempts to bypass or break through such safeguards.

A firewall is a network security device or software that monitors and filters incoming and outgoing network traffic based on predefined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. Firewalls are used to prevent unauthorized access, block malicious traffic, and allow safe communication between systems, thereby playing a critical role in protecting networks from cyber threats.

To secure a server, the first step would be to keep the operating system and all software updated with the latest security patches. Implementing strong password policies and enabling multi-factor authentication helps to strengthen user access control. Configuring a firewall and intrusion detection or prevention system would further protect the server from external attacks. Regular data backups and encryption of sensitive information are essential to ensure data integrity and availability in case of a security breach. Limiting user privileges and continuously monitoring server activity are also crucial practices to maintain a secure environment.

Cyber crime refers to illegal activities conducted through computers and the internet, including hacking, identity theft, phishing scams, and spreading malware. Cyber security, on the other hand, involves practices and technologies designed to protect systems, networks, and data from such malicious activities. It encompasses a wide range of measures such as implementing secure network configurations, data encryption, and user education to safeguard against cyber threats and ensure the confidentiality, integrity, and availability of information.

Good cyber security operates by combining multiple layers of defense across devices, networks, and data. It involves continuously monitoring systems for potential threats, applying timely software updates and patches, using encryption to protect sensitive data, and enforcing strong access controls. In addition, educating users about safe online practices helps to prevent attacks like phishing and social engineering. Effective cyber security is proactive and adaptive to evolving threats, ensuring an organization’s digital assets remain secure.

The best way to train for cyber security is by pursuing professional certifications such as CompTIA Security+, Certified Ethical Hacker (CEH), or Certified Information Systems Security Professional (CISSP). Practical experience in labs and virtual environments enhances hands-on skills, while staying informed about emerging threats helps keep knowledge up to date. Participating in cyber security competitions and workshops also builds real-world expertise. Continuous learning and practice are essential to remain effective in the fast-changing cyber security landscape.

The costs of a cyber attack can be severe and wide-ranging. Organizations may suffer significant financial losses due to theft of funds, ransom payments, and business downtime. A damaged reputation can lead to loss of customer trust and decreased business opportunities. Legal consequences and regulatory fines for failing to protect data can also add to the financial burden. In addition, the operational disruption caused by cyber attacks can slow down productivity and require substantial resources to recover and restore systems.

Mobile devices do present security risks because they are often used on public networks, making them vulnerable to eavesdropping and attacks. They can be easily lost or stolen, exposing sensitive data to unauthorized access. Many users also neglect to update their devices regularly, leaving them open to exploitation. To mitigate these risks, mobile devices should be secured with strong passwords, encryption, and updated security software, and users should avoid connecting to untrusted networks.
