Viruses, spyware, malware, hackers, and identity thieves are examples of common cyber security dangers. No company, no matter how big or little is safe from these dangers. In fact, small firms are frequently an appealing target since their defenses may be weaker, especially as cybercriminals develop increasingly automated attacks. According to a recent study by the Small Business Technology Institute, many firms don't have enough security control over even the most fundamental services, like email. 56% of the firms in the survey had at least one security issue in the previous year. These attacks typically cost thousands of dollars, create major time losses, and disrupt services. Here are 10 methods to make computers and networks more secure.
Use Effective Passwords and Change Them Regularly
Create a separate user account for each employee and require password protection and strong passwords. Strong passwords are at least eight characters with a combination of upper and lowercase letters, numbers, and symbols. Change passwords at least every three months and don't reuse old passwords. Do not post passwords anywhere or share them with anyone.
Secure Wireless Networks
Upgrade from the default WEP encryption standard to the much stronger WPA2 standard and enable MAC address filtering. Don't use default passwords to protect access to your router. Hide your network name from drive-by hackers by disabling Service Set Identifier (SSID) broadcasting.
Install, Maintain, and Apply Antivirus Programs
Enable the antivirus software auto-update feature. Check all portable media for viruses prior to accessing them.
Install and Use a Firewall
Establish a policy on what your firewall will allow getting through. Use both software and hardware firewalls. Use content filters to prevent access to sites most likely to contain threats.
Don't Open Emails or Attachments from Unknown Sources
Be suspicious of unexpected emails containing attachments from unfamiliar sources; these should be phishing attempts or contain ransomware. Be suspicious of emails that are not work-related, have unusual subject lines, or contain links Establish a strict policy on what can and cannot be downloaded.
Remove Unnecessary Programs
Periodically review all the installed programs. Remove any unused programs by uninstalling them.
Control Access to Computer Equipment
Log off or apply a screen lock before leaving your computer and use password-protected screensavers. Install security applications on mobile devices to prevent information theft when on public networks.
Secure computers with security cables
Secure computers with security cables and store sensitive media in a locked cabinet or drawer. Secure routers and servers out of reach of customers or visitors, ideally in a locked room. Lock empty office and conference rooms where active network connections are located.
Create Backups Automatically
Backup data automatically, if possible, or weekly at a minimum. Store backups off-site or in the cloud and test periodically to ensure the files are accessible.
Stay Current with Software Updates
Regularly update software, including operating systems and browsers. Use automatic updates and restart the computer after patches are installed.
Establish basic security practices
Establish basic security practices and policies and resulting disciplinary actions. Establish procedures for protecting customer information and other vital data. When needed, get technical expertise and outside help. Before hiring help, consider the company's client lists, references, and how long they've been in business.
