What is cyber security & how does it affect your organisation?
What is cyber security?
Cyber security is defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks.
How can it affect your organisation?
- Ransomware: attackers demanding payment after encrypting files (making them inaccessible). Even paying the ransom does not guarantee the recovery of encrypted data.
- Phishing: receiving emails, texts or phone calls from attackers purporting to be from a reputable company so they can gain personal/sensitive information i.e. credit card numbers & account logins. (Social Engineering can be used to manipulate victims so the attacker can gain access e.g. leaving a USB stick with malware on in a car park).
- Malware: Any file or programme intended to harm a computer, this includes; trojans, worms, viruses & spyware. Using outdated (unpatched) software such as Windows XP/Vista opens you & your organisation up to opportunities for attackers to target known vulnerabilities & potentially disable your whole system.
How can you protect yourself?
- Next Generation Antivirus (NGAV): Malware can spread from machine to machine by using a network connection, NGAV protects droves, processors & PCs.
- Email Server Certification: This verifies that emails that purport to come from your server, are coming from you and are not a scam to fool your contacts.
- Email Antispam/Anti-phishing: These can help detect unsolicited emails/phishing content and block them from reaching your server.
- Firewall Configuration: This helps filter incoming/outgoing network traffic and controls access to your network and servers.
- Strong Wi-Fi Encryption: This encrypts data as it travels in & out of your network via Wi-Fi making it more difficult for the data to be read or altered by attackers
