Spam emails have been around for two decades and they become more deceitful and destructive each year. They started out as marketing emails selling diet pills or body enhancement drugs. As time went on, they evolved into something more devious by tricking users into providing their bank account details in exchange for a large sum of money.
IT support companies suggest that businesses receiving regular spam should consider installing an email filtering system. This system can protect them from any email-based threats.
In addition to obtaining an email filtering system, companies can also perform these actions to protect against spam:
Educate Employees about Spam
Companies, especially financial institutions, should conduct information security awareness training with the goal of providing employees instructions on recognizing and dealing with suspicious emails.
Apart from training, companies can also establish information security policies in the workplace. Policies, such as “when it doubt, throw it out”, can minimise the risk of opening a suspicious link from a spam email.
Patch Security Vulnerabilities
Some spam find and exploit vulnerabilities in a computer or network server. To address these vulnerabilities, companies can either install the latest enterprise anti-virus or download security updates provided by the operating system.
When selecting an anti-virus program, companies should refrain from installing free anti-virus brands found on the web. They provide very limited protection and may not effectively shield computers from server attacks.
Configure Administrative Privileges
It is essential that companies set up user accounts with the appropriate administrative privileges. Some well-coded spam target and take full control of vulnerable user accounts. Those in the senior management level, such as directors and managers, should have encrypted access controls that will serve as an extra layer of protection from hackers.
Users initially took spam for granted since they were not dangerous at the time. Most of these emails now contain viruses and malware and users take them seriously by protecting themselves from these threats.
