Prevent Social Engineering Attacks (Prevention Techniques)

In the age of advanced cyber security solutions, firewalls, and multi-factor authentication, it's easy to overlook a different type of risk to information security: the human element.

Social engineering attacks, which exploit human psychology to elicit sensitive information or compromise security, are becoming increasingly common and sophisticated. From phishing emails that seem to come from trusted colleagues to impostors masquerading as IT personnel, social engineering attacks take on various forms and present organizations with a multiplicity of challenges.

This article explains everything you need to know about social engineering attack prevention, including the most efficient techniques for protecting your data from these malicious attempts as a business and as an individual.

How Can Businesses Prevent Social Engineering Attacks?

Businesses must integrate technological solutions with education on social engineering to protect themselves from these attacks.

Here are the methods you can implement to prevent a social engineering attack.

1. Performing Regular Security Awareness Checks

Providing regular security awareness training to their employees ensures that companies strengthen the first line of defense against social engineers. They must educate their personnel on potential social engineering attacks they could be exposed to, such as spear phishing, pretexting, tailgating, and other similar tactics. By learning to recognize the telltale signs of these attacks, employees work together to block social engineering attempts and protect the organization.

A crucial part of security awareness training is performing vulnerability assessments to check the company’s preparedness for potential attacks. Simulations and mock social engineering attacks test not only the efficiency of your tech solutions but also the knowledge of the employees on this matter. Employees who do not pass these assessments should retake the training to boost their skills in identifying social engineering attacks.

The importance of security awareness training is underscored by the fact that over 85% of cybersecurity breach incidents result from human error, according to Verizon. This shows that even the most advanced technology needs to be complemented by cyber-educated and quick-thinking staff.

2. Enhancing Access Protocols

Ensure that only authorized personnel have access to information and perform regular identity checks, especially if you suspect that an unauthorized attempt is taking place. Multi-factor authentication is an effective layer of protection against malicious attacks because it requires additional confirmation before granting access.

When it comes to money transfers, it is smart to require additional confirmation before initiating any financial transaction. For example, demand a face-to-face confirmation before authorizing transfers over a certain amount. These protocols provide essential protection against social engineering attacks by directly addressing the errors humans make in daily interactions, which can put their companies in danger.

3. Conducting Email Filtering

Email filtering is an essential tool for preventing phishing and its subtypes, such as whaling, a social engineering method that targets company executives. Successful email filtering solutions can detect malicious content and flag it as suspicious before you open the email.

Email filtering also relies on sender verification, which detects suspicious domains and blocks their message or sends them directly to the spam folder. This stops users from accidentally clicking the message and engaging with harmful content. Some advanced email filtering solutions track “normal” behavior from trusted or frequent contacts. This helps them detect and flag unusual communication.

Verizon’s 2021 Data Breach Report states that 94% of malware was delivered by email. This, and the fact that an estimated 3.4 billion phishing emails are sent daily, highlights the importance of email filtering as a preventive solution.

4. Employing an Incident Response Plan

Companies should have a detailed incident response plan in place for when a social engineering attack happens. This includes the steps to take to resolve the situation and prevent further damage to the company and its resources.

All incidents should be documented for further analysis and communicated to key personnel through appropriate channels. This allows the organization to respond more effectively if a similar incident occurs and highlights weaknesses in both the system and the human element that require closer attention.

5. Performing Regular Monitoring and Audits

Monitoring all network activity is one of the most efficient ways to detect and prevent a social engineering attack. Suspicious behavior should be reported to authorized personnel and analyzed to create an adequate solution before damage is done. These solutions should assess not only technical activity but also user behavior. For instance, an employee attempting to access the system at an unusual time, outside their usual working hours, should raise a red flag.

Regular audits help the organization identify weak spots in its systems and areas that could use improvement. They also check for compliance with the latest regulatory and industry standards, which significantly enhances data protection. Some companies hire third-party auditors who perform additional checks with a fresh pair of eyes.

6. Relying on Endpoint Security

Endpoint security ensures that all devices used by employees are protected with the latest antivirus, anti-malware, and other security solutions.

Endpoint devices such as computers, tablets, and work mobile phones are protected against social engineering attacks in several ways:

• Preventing access to unsecured websites and downloads of apps from unverified sources on company devices.
• Encrypting and regularly backing up all data ensures it remains inaccessible, even in the event of an attack.
• If the device is stolen or lost, the system should include a feature to remotely wipe all data to keep it protected.

7. Not Disregarding Physical Security

Only employees should have access to office spaces, server rooms, and company buildings. Staff must log all entries and exits, and security badges and biometrics should manage their access, particularly to areas containing sensitive data. Companies must set up surveillance systems within their premises to continuously monitor access.

Physical security is essential because it complements cyber security measures. For example, server rooms that house sensitive data must be physically secure to prevent unauthorized access that could lead to data breaches. It's not enough to have firewalls and encrypted networks; if someone can walk right in and access a terminal, then digital security measures are rendered useless. The same applies to the daily work habits of employees. If an employee leaves their workstation unlocked, it creates an opportunity for data abuse, theft, or malware installation.

How Can Individuals Avoid Falling Victim to Social Engineering?

Social engineering attacks begin when an individual falls for a trick, granting access or providing information they shouldn’t have.

Here is a list of the ways individuals can protect themselves from social engineering attacks.

1. Remain on alert. Individuals should remain vigilant for suspicious behavior. If something seems off in your daily interaction, either online or in person, it is safer to report it to authorized personnel who will take care of the rest.
2. Use strong passwords. Make sure your passwords are strong and changed regularly. Do not share them with anyone, not even if someone claims to be IT personnel.
3. Limit online information sharing. This applies not only to company but also personal information. Be cautious about how you share your data online, including via email and social media.
4. Verify all contacts. If someone claims to be a person of authority and asks for sensitive information, verify their identity through official channels, not just the contact details they provide.
5. Monitor personal account statements. By regularly checking your bank statements for suspicious activity, you can prevent unauthorized transactions and financial losses.
6. Secure physical access. Ensure your workstation is always locked before leaving your desk, and never share your security badge with anyone else.

Building a Defense Against Social Engineering

As cyber threats grow in volume and sophistication, it is crucial to remember that the strongest firewall and the most complex encryption algorithms are only as effective as the people who use them. Individuals should take every precaution to avoid being the weak link in the security chain.

Companies should have a foolproof strategy that includes regular staff training, strictly enforced security protocols, and the latest technological solutions to mitigate the risks of attacks. phoenixNAP provides security features for your data and networks to keep your business covered and successful.
