Cyber attacks and cyber security: All you need to know


Evolution of cyber attacks

Over the past decade, cyber attacks have evolved in complexity and impact. A few of the significant changes include the rise of ransomware, blatant attacks on critical infrastructure, and the emergence of supply chain attacks.

High-profile incidents like WannaCry in 2017 highlighted the global reach of cyber threats. The SolarWinds supply chain attack in 2020 demonstrated the potential for compromising widely used software to infiltrate numerous organisations.

Additionally, the increasing frequency of state-sponsored cyber operations has raised concerns about the merging of cyber and geopolitical tensions. The constant evolution of attack techniques, from phishing to more sophisticated tactics, keeps cyber security professionals challenged in their efforts to defend against cyber threats.


Secure your data with physical & logical security

Physical data security involves safeguarding data through tangible measures, often focusing on the protection of physical assets that store or transmit information. This includes securing servers, data centres, and other hardware components. Physical security measures may include access controls, surveillance systems, locked cabinets, and environmental controls like fire suppression systems to protect against physical threats such as theft, vandalism, or natural disasters.

Logical data security, on the other hand, is concerned with protecting data at the software and system levels. It involves measures like encryption, access controls, authentication mechanisms, and intrusion detection systems to safeguard data against unauthorised access, modification, or deletion. Logical security focuses on securing the digital pathways through which data travels, ensuring that only authorised users or systems can interact with sensitive information.


Impact of cyber attacks

  1. Data breach: Cyber attacks often result in unauthorised access to sensitive data, leading to data breaches. This can expose personal information, financial records, or intellectual property.
  2. Financial loss: Businesses may incur significant financial losses due to the costs associated with recovering from an attack, compensating affected parties, and potential legal ramifications.
  3. Reputation damage: A cyber attack can severely damage an organisation's reputation. The loss of trust from customers, clients, and partners may have long-lasting consequences.
  4. Operational disruption: Cyber attacks can disrupt normal business operations, causing downtime and affecting productivity. This is particularly impactful in industries where continuous operation is critical.
  5. Intellectual property theft: Cyber criminals may target intellectual property, trade secrets, or proprietary information, leading to a loss of competitive advantage for businesses.
  6. Regulatory consequences: Non-compliance with data protection regulations may result in legal consequences and financial penalties. GDPR, for example, imposes substantial fines for mishandling personal data.
  7. Cyber security costs: Organisations often need to invest significantly in cyber security measures, including implementing advanced technologies, training staff, and conducting regular security audits.
  8. Supply chain disruption: Cyber attacks on supply chain partners can have a cascading effect, disrupting the operations of interconnected businesses and causing a ripple effect throughout the industry.
  9. Identity theft: Individuals may become victims of identity theft as a result of compromised personal information, leading to financial losses and damaged credit.
  10. National security threats: Cyber attacks can extend beyond the private sector, posing risks to national security. Critical infrastructure, government systems, and defence networks are potential targets with severe consequences for a nation.

How to protect your data from vulnerabilities & attacks?

  1. Use strong authentication: Implement multi-factor authentication (MFA) to add an extra layer of security beyond passwords. This makes it harder for unauthorised individuals to access your accounts.
  2. Regularly update software: Keep operating systems, antivirus programs, and applications up-to-date with the latest security patches. Software updates often address vulnerabilities that could be exploited by attackers.
  3. Encrypt sensitive data: Protect sensitive information using encryption not only where it is stored but also when it is being shared and en route. This ensures that even when the data is vulnerable and may be accessed by a third-party, it remains unreadable without the appropriate decryption keys.
  4. Train employees: Educate your staff about cyber security best practices. Phishing attacks often target individuals through deceptive emails or messages, and awareness training can help employees recognise and avoid such threats.
  5. Implement access controls: Keep access to sensitive data on a need-to-know basis. Provide access only to the data that the individual requires to fulfil their job responsibilities.
  6. Regularly backup data: Perform regular backups of critical data and ensure that backup systems are secure. In the event of a ransomware attack or data loss, having up-to-date backups can facilitate recovery.
  7. Network security measures: Employ firewalls, intrusion detection systems, and antivirus software to protect your network from unauthorised access and malware.
  8. Periodically perform security audits: Regularly assess your systems and networks for vulnerabilities. Security audits can help identify and address potential weaknesses before they are exploited.
  9. Create an incident response plan: Develop a comprehensive incident response plan to efficiently and effectively address security incidents. This plan should outline steps to take in the event of a data breach or cyber attack.
  10. Stay informed about threats: Keep abreast of the latest cyber security threats and trends. This awareness enables you to ensure that your cyber security system is able to effectively safeguard your data from evolving risks and vulnerabilities. The ideal holistic cyber security strategy will have a mix of technical measures, educating employees, and constant monitoring enabling proactive, and preventive actions.

Cyber attacks are constantly evolving and becoming more sophisticated, often involving advanced technology and organised collaboration. As a result, many individuals and organisations are finding themselves vulnerable to these attacks. However, cyber security is also advancing and improving to deter, identify, mitigate and protect both physical and logical assets.
