Reasons To Integrate DLP With Cloud Access Security Broker

Cloud based services play an important role in providing greater flexibility and access to core business applications. However, a major drawback of cloud computing is that the information stored and shared through these systems is highly vulnerable.  To tackle this vulnerability, cloud access security broker (CASB) solutions are being adopted by organizations for protecting data stored in both sanctioned and unsanctioned cloud applications. CASB can be installed on-premises or a cloud-based version of the software can be used as a security layer between the cloud application and service users to monitor the activity & enforce security measures. Another set of tools that is widely used by organizations to prevent data loss is DLP. Data Loss Prevention (DLP) tools classify the regular and critical data & identify security violations.

Cybersecurity firms are integrating CASB and DLP solutions to monitor & control sensitive data. This integration acts as a control point between users, accessible cloud services and the data stored in the cloud. Integrating DLP with Cloud Access Security Broker offers advantages like real time data protection and access management.

Following are other reasons to be considered for integrating DLP with CASB:

  • A rising number of businesses are falling victim to cyber-attacks and data breaches. Cyber criminals are targeting enterprises with malware attacks designed specifically for cloud platforms. They take advantage of loopholes like poor configurations, unauthorized devices and ill-defined access management because IT departments are not able to provide DLP coverage to these blindspots of cloud storage. However, integrating DLP with CASB solutions will help in providing comprehensive DLP coverage to protect sensitive data stored in the cloud.
  • >With the changing cyberattack scenario, it is essential to continually evolve industry’s response to these attacks. Standard network to endpoint workflow should no longer be assumed enough for protection against new and sophisticated malware attacks. Both DLP and CASB may have overlapping features but they fall short on cloud coverage and comprehensive coverage respectively. Thus, it is impossible to get complete cyber security coverage with just one solution. Integrating both solutions provides enhanced coverage to the cloud service users.
  • Integrating DLP and CASB is simple and easy. To integrate with a DLP solution, CASB uses ICAP protocol that sends the content to DLP for review. The DLP inspects files against its existing policies. Once a violation is identified, it sends the violation to the CASB cloud platform via the connector software. The CASB cloud platform enforces remediation action with the cloud service via API.

Most organizations are integrating DLP with CASB as a security standard to protect their data from impending threats.

Rising Security Threats

Cybersecurity threats are not new; however, they have gained momentum as the intensity and volume of attacks has increased in recent years. A mix of sophisticated old threats and new zero-day attacks have given rise to the need for new cyber security techniques.

In order to formulate effective cyber security strategies, it is important to understand different types of rising security threats:

  1. Insecure API: API refers to Application Programing & User Interface. When an organization sources a cloud service from a service provider, the interface is not used by a single client. It is shared by numerous other users; thus, the organization cannot control the security of interface. As a client, organizations should make sure that the service provider incorporates stringent security measures starting from authentication to encryption.
  2. Direct Data Center & Cloud Attacks: The cyber attackers launch these attacks by locating vulnerabilities in applications and exploiting them to enter a cloud network. Generally exploited vulnerabilities are insecure passwords and lack of proper authentication. Once the cyber attackers gain access, they can move across the applications & data centers freely. Such attacks are not easily spotted by the compromised organizations.
  3. Crypto-jacking: As cryptocurrency is gaining popularity, cryptocurrency attacks are also rising. Crypto-jacking is the term used for unauthentic use of someone’s computer for mining cryptocurrency. The crypto mining code is either encrypted in a link which is sent to the victim via a phishing e-mail or it is loaded in an infectious online ad or website. Once the user clicks on the link, the code is installed on his computer. However, in case of infected ad or website, the code is not loaded on victim’s computer. As the website or ad pops up in victim’s browser, the code is auto-executed. Unlike ransomware, crypto mining code does not harm user’s personal data but uses CPU resources which results in slow processing.
  4. Advanced Persistent Threat (APT): In APT, the hacker breaches a network but stays undetected for a long time; thus, increasing his dwelling period instead of asking for instant ransom. The main motive is to steal information or security data unobtrusively. The breach could be caused by using malware, exploit kits or by piggybacking on legitimate traffic. Once breached, the attackers could steal login credentials to move across the network easily.
  5. IoT Attacks: IoT now includes laptops, tablets, routers, webcams, smart watches, wearable devices, automobiles, home electronics, etc. As IoT is becoming more ubiquitous and number of connected devices is increasing, cyber criminals are targeting the IoT networks for cyber invasions & infections. Once they gain access to a network, cyber criminals can program the devices to create chaos, lock down essential devices for financial ransom, overload the network, etc.

With rising cyber security threats, organizations need to follow strict data management and security practices to protect their data.

Gap Between Traditional EDR & Modern Threats

The term End Point Detection & Response (EDR) was first coined by Anton Chuvakin in July 2013. It is used to define ‘the tools that are primarily focused on detecting and investigating suspicious activities (and traces of such) other problems on hosts/endpoints’.

EDR works by collecting data related to endpoint events using a software. This data is sent to a centralized database where further analysis, investigation & reporting is conducted by analytical tools. These tools pay heed to both internal as well as external threats. They respond to these threats while identifying the upgrades required for strengthening the organization’s cyber security. The traditional EDR tools have been successful in creating visibility and remediation of stealthy threats. However, the cybercrimes have evolved and this has led to a need for better and evolved EDR tools.

Following are some gaps between traditional EDR and modern threats that have given birth to the need for next-generation solutions:

  1. EDR requires cloud connectivity and an analyst has to wait for cloud response to take action. This results in a delay in protecting end devices. However, the cyber threats no longer target a single user and are capable of spreading over the entire organization, encrypting data and removing traces of attack in mere seconds.
  2. The attackers make use of tools already available on a computer to incorporate scripts that run directly in the memory. These in-memory file-less attacks do not leave behind a trail and may not be detected by traditional EDR tools.
  3. To provide visibility, EDR creates a high amount of data and analysis; thus, these solutions are not scalable and require extensive resources like bandwidth, skilled workforce, etc.
  4. EDR does not provide visibility into lateral network. If a threat makes its way into organizational network, it can move through connected devices and covertly communicate with a remote control server without being detected or interrupted.

In the world of ever developing cyber threats, it has become important to make a shift towards next generation EDR solutions that make use of artificial intelligence to detect threats in real time. It is advisable to use a collaboration of various security solutions to create a multi-layer cyber security shield. New EDR solutions offer wider features:

  • Detect and prevent hidden exploits that are more complex than a simple hash signature.
  • Visibility throughout applications, endpoints, processes & communications to detect malicious activity.
  • Automation of alerts & defensive responses once an attack is detected.
  • Threat intelligence and forensic capabilities to gain information about movements of the attacker in the network.
