Why you should ensure data security in remote access?
As more employees opt for remote work, ensuring strong data security practices becomes vital for any organization. However, the remote work environment has given adversaries an easy target. Employees without sufficient knowledge of data security can fall victim to phishing, ransomware, or malware injections. To prevent your network from being compromised, it is best to implement data security measures and educate employees about the threats.
Most common adversarial attacks
Educating the employees on the most common ways adversaries target the network is a crucial step in ensuring data security. Here are some of the common adversarial attacks that need to be looked out for.
- Phishing: Phishing attacks involve tricking individuals into revealing sensitive information such as passwords, credit card numbers, or other personal data by impersonating a trusted entity via email, text message, or other communication channels.
Phishing is the most common adversarial attack and thus, employees need to be educated to distinguish between legitimate websites and phishing sites. - Malware: Malware, short for malicious software, is designed to infiltrate or damage a computer system. This can include viruses, worms, trojans, ransomware, and spyware. There are many types of malware, each with varying severity.
Ransomware and spyware are some of the most common types of malware. Ransomware encrypts all your important files demanding payment for the decryption key, while spyware secretly collects information from a computer or device without the user’s knowledge or consent. - Denial of Service (DoS) and Distributed Denial of Service (DDoS): DoS and DDoS attacks overwhelm a target system or network with a flood of traffic, rendering it inaccessible to legitimate users. These attacks can disrupt services, cause downtime, and impact business operations.
These aren’t the only types of attacks out there. But it helps employees identify some of the most common adversarial attacks.
Best practices to keep your network safe
Data Security Practices
Here are some of the practices that you should follow to keep your data safe in remote access:
Remote monitoring
Remote monitoring plays a critical role in enhancing security, allowing swift incident response and mitigation. Remote monitoring solutions enable organizations to monitor network traffic, detect anomalies, and identify security breaches in real time.
By leveraging remote monitoring solutions effectively, organizations can gain insights, enhance decision-making capabilities, and stay ahead of the curve in today’s dynamic and competitive digital landscape.
Network Segmentation and Network Access Control
- Network Segmentation: This is a cybersecurity strategy that involves dividing a computer network into smaller, isolated subnetworks called segments. Each segment is logically separated from other segments, typically using network security controls such as firewalls, routers, and VLANs. By segregating critical assets, sensitive data, and high-risk systems into separate segments, organizations can contain and mitigate the impact of security breaches and cyberattacks.
- Network Access Control (NAC): NAC solutions enforce security policies and authentication mechanisms to ensure that only authorized users and devices can connect to the network. It involves technologies such as authentication, authorization, and enforcement mechanisms.
Security auditing
Security audits should be conducted to detect vulnerabilities. They are essential for assessing and improving an organization’s security posture, ensuring compliance with regulatory requirements, and mitigating security risks effectively.
Maintaining an audit trail helps in ensuring data security, an audit trail is a chronological record of events or activities that occurs within an organization’s network. An audit trail comes in handy when you need to trace the source of a breach or threat.
Data encryption and Multi-Factor Authentication:
- Data encryption: Data encryption is a fundamental security measure that protects sensitive information by converting it into an unreadable format, which can only be deciphered by authorized parties with the appropriate decryption key.
- Multi-Factor Authentication(MFA): It is a security mechanism that requires users to provide two or more authentication factors to verify their identity before granting access to the network. MFA enhances security by adding an extra layer of protection aside from username and password authentication.
Technologies used for remote access security
Various technologies are used in remote access security to strengthen an organization and provide a layer of protection against attacks. Here’s some of the most prominent ones.
- Virtual Private Networks(VPNs): VPNs establish encrypted tunnels over public networks, such as the internet, to securely transmit data between remote users and corporate networks. They provide secure access to internal resources by encrypting all traffic between the user’s device and the corporate network, protecting against interception.
- Identity and access management (IAM): IAM solutions centralize user authentication, authorization, and access control, ensuring that only authorized users can access resources remotely. They provide centralized management of user permissions, helping organizations enforce principles and maintain security compliance.
- Endpoint security solutions: Endpoint security solutions such as antivirus software, firewalls, and endpoint detection and response (EDR) tools protect remote devices from malware, intrusions, and other security threats. They help enforce security policies, detect suspicious activities, and prevent unauthorized access to sensitive data on remote devices.
Recommended tools for data security in remote access
There are many tools in the market that help with implementing data security in remote access; the ones we recommend include AD360.
AD360 helps with many of the features discussed in the article such as, Identity management, Access Control, Auditing and Authentication. These capabilities help organizations mitigate the risks associated with remote work and safeguard sensitive data from unauthorized access or breaches.
