    Safeguarding an organization against insider threats and maintaining robust data security, information security, and cybersecurity is becoming increasingly challenging in the era of remote work. With employees working from diverse locations and networks, it’s critical to implement stringent best practices for remote work security:

    • Secure VPNs: Virtual Private Networks (VPNs) are pivotal in securing remote work environments. They establish encrypted connections between remote devices and the corporate network, ensuring that data transmitted remains confidential and protected from potential insider threats.
    • Two-Factor Authentication (2FA): Implementing 2FA is a non-negotiable aspect of remote work security. This additional layer of security requires employees to provide two forms of identification before accessing company resources. It’s a strong defense against unauthorized access and potential insider threats.
    • Regular Security Training: Remote staff must be well-versed in security protocols and practices. Regular security training sessions are vital to keep employees updated on the latest security threats and best practices.
    • Endpoint Security: Endpoint security solutions protect individual devices, such as laptops and smartphones, from security breaches.
    • Data Encryption: Encryption is a fundamental technique for data protection. All data, whether at rest or in transit, should be encrypted to mitigate the risk of data breaches. This practice ensures that even if data falls into the wrong hands, it remains indecipherable.
    • Regular Updates and Patch Management: Keeping all software and systems up to date is critical for remote work security. Regular updates and patch management mitigate vulnerabilities that could be exploited by insider threats or external attackers.

Employee Departures and Offboarding

Employee departures, whether voluntary or involuntary, can pose significant risks related to insider threats. It’s crucial for organizations to manage these situations effectively, safeguarding their data security and information security.

  • Managing Insider Threat Risk During Employee Departures

    Implementing strict offboarding procedures is crucial in reducing the potential risks associated with departing employees. This step is a critical component of robust cybersecurity practices. When an employee leaves, organizations must ensure that all their access privileges are revoked promptly.

  • Revoking Access and Data Recovery

    One of the primary tasks during employee departures is promptly revoking access to systems and data. This action is fundamental for safeguarding data security. Additionally, data recovery may be necessary to ensure that no critical information is lost during the transition. Such practices should be ingrained in an organization’s cybersecurity protocols.

Is your contact center safe from your employees?

Like all organizations, call centers are most vulnerable from the inside. Unfortunately, many of them are quick to direct their vigilance toward external threats, which is actually good until it starts to leave massive internal loopholes.

potential data security vulnerability call center employees at work

It doesn’t help that internal data security is often overlooked by managers who are complacent with their existing defenses. Contact centers, in reality, are at a higher risk than other companies when it comes to threats brewing from within its walls. Mainly, it’s due to the voluminous amounts of data that employees are constantly exposed to.

It’s easy for eavesdropping maintenance crew, sneaky agents, and prying IT experts to give in to the allure of siphoning customer information illegally. Worse, they’re already too familiar with the company’s security measures, making it easier for them to get through the cracks.

So how do you protect your call center when the threats of data breach could be coming from the inside? Here are the areas you must pay attention to.

  1. Background checks

    This might already be a routine task for your recruitment team, and it may also be why managers usually take it for granted. It might be wiser to take your background checks a step further. You may get in touch directly with applicants’ previous employers so you can ask about their history. Looking at their social media pages is also a good idea.

    Also, watch out for behavior red flags. For example, those who lack dedication and loyalty may be more likely to commit fraud than happy, productive employees.

  2. Access to sensitive customer data

    For contact centers, the question of how much data access should be granted to employees will always spark debates. Several factors should be considered when you’re trying to decide about this. For instance, you need to assess how much information your agents need to provide excellent customer service. Allowing a wider access than necessary is a risk you can’t take, whereas limiting the information employees can view may disrupt customer support.

    Data access also varies from one department to another, depending on their duties.

  3. High attrition rates

    Most internal data security crimes are plotted by agents who are about to leave a company. If there’s a heap of resignation letters on your desk, your company may be at immediate risk. Plus, this means more employees will be entering your office soon to replace the ones who have left, which increases the information risks even more.

    As a solution, investing in the happiness of your employees fosters loyalty, therefore guarding you against these threats.

  4. Computer and network activities

    Yes, you have to monitor your employees’ behavior, but how do you do that? You can start by looking at how they use your network and computers.

    Your agents should be using roughly the same applications and accessing the same databases. But if someone starts deviating from their usual pattern, there could be something wrong. Watch out for copied or moved files, questionable use of private browsing modes, and possible tampering with data security measures.
