Cyber-attacks are becoming more sophisticated and it is no longer just large corporations that are being targeted. Small and medium-sized businesses are often targeted because attackers assume a lower level of security.

A successful attack can lead to sensitive data leakage, identity misuse, systems downtime or financial loss. Therefore prevention is one of the most important elements of cyber security.

How to protect yourself from hacker attacks?

Effective prevention doesn’t just mean having an antivirus. It’s about a comprehensive system of protectionthat combines technology solutions, policies and employee education.

1.Protecting emails

Email is one of the most common attack vectors. The most common techniques include:

  • phishing messagesposing as trusted sources,
  • harmful attachments or linksthat trigger malware,
  • spear phishing, targeted attacks on specific employees.

Reliable email protection includes:

  • filtering spam and suspicious messages,
  • real-time checking of attachments,
  • use of secure email gateways,
  • introduction of DMARC, DKIM and SPF records.

2.Data encryption

Even if the attacker gets access to the data, encrypt can prevent their misuse. It is advisable to encrypt:

  • discs and devices, in particular laptops and portable drives,
  • communication – e-mails, messages, transmissions within the network,
  • data in the cloud and on local servers.

Strong encryption (e.g. AES-256) ensures that data remains unreadable even in the event of unauthorized access.

3.Detection of suspicious activities

Modern systems allow early detection of attacks before they cause damage. Detection of suspicious activities (anomaly detection) includes:

  • tracking user and system behaviour,
  • detecting non-standard access, excessive traffic or suspicious login attempts,
  • automatic alerts and incident response.

Such solutions can operate as stand-alone tools (e.g. SIEM) or be part of security suites.
