Common misconceptions about home networks are that their home networks are too small to become targets or devices come preconfigured to be secure out the box. When a network is connected to the internet, it is vulnerable to cyber attacks. Implementing multiples types of security measures can help mitigate becoming a victim of online attacks.
Implementing defense-in-depth at home
- Install end device firewalls and antimalware software.
- Remove unnecessary services and software.
- Update your software regularly!
Router / Modem
- Change default log-in passwords to your home routers. Most default passwords can be found online for you routers.
- Adjust factory default configurations. Most products are overly permissive out the box.
- Update all firmware and install a network firewall. Firewalls serve as the first line of defense, defending against external threats.
- Disable WPS, SSID broadcasting and remote management.
- Using WPA3 for your routers passphrase.
Browser / online safety
- Keep your browser up-to-date.
- Only visit secure websites that use https.
- Avoid clicking Ads and offers, as they can redirect you to a malicious site.
- Do not click on links to websites you do not recognize or links in emails.
“Security is not a product, but a process.” -Bruce Schneier
Cyber Security Statistics
(2021 Cyber Security Statistics Trends & Data, 2021)
- The education industry is ranked last in cyber security preparedness out of 17 major industries.
- Ransomware attacks are estimated to cost $6 trillion annually by 2021.
- 98% of cyber attacks rely on social engineering.
- 50% of phishing sites now using HTTPS.
- It takes organizations an average of 191 days to identify data breaches.
- 21% of all files are not protected in any way.
What I’ve learned is to be proactive and not reactive. Insecure data at rest is more vulnerable to cyber attacks and it can be avoided if the necessary precautions are taken.
No network will ever be 100% impenetrable but taking the time to secure your home network can definitely deter a would-be attacker. Use high diligence when it comes to protecting your assets because any serious cyber threat can be life changing.
