Enterprise Security: Threat Detection, Prevention and Response
Enterprise security is critical for every business as cyber threats are emerging in different forms and pause threats despite the size of the organization. When the organization’s security is compromised, the customers are also at risk since they might have shared their private information including financial data. Based on the business they are in, organizations gather information from the customers such as banking details, credit card/debit card details, PAN number, email address, phone number, and so on. Enterprises are bound to protect the privacy of not only the customers but also the employees as per the data privacy laws.
Enterprise Security: An Overview
Enterprise security can be defined as the actions taken by the company to secure data or information assets stored in their servers. The security processes devised by the organization includes various policies and methodologies that provide regulations to protect their interest from the infringement of integrity, confidentiality or rights.
An Enterprise Risk Management process is essential to execute the processes or activities for implementing high-level security in enterprises. This includes the identification of existing threats and vulnerabilities and devising a plan to mitigate the security risks. Based on the changing scenario of ever-evolving businesses, the enterprise risk management program also should be evaluated continuously and upgraded to safeguard the organization from future cybercrimes.
Importance of Enterprise Security
Today, a majority of businesses are vulnerable to cyberattacks and an effective cyber risk management program is mandatory to secure the network infrastructure. Without having an operational risk assessment program, enterprises are exposed to malicious threats from different threat vectors. The network security should be taken care across networks, devices, applications, data, servers, and end-users. The risk management program enables the enterprises to develop threat detection, prevention and response solutions to identify and respond to various threats in real-time.
Cyber threats or cyberattacks consist of data breaches occur to harm the systems or network of the organization. Threat detection is the capability of the organization to identify networks, applications or data threats within the organization accurately and quickly. It must be the first priority of the security team to formulate a plan to implement various technologies for detecting threats within the network. Some of the technologies used in threat detection are Endpoint Detection and Response, Cloud Access and Security Brokers, Intrusion Detection Systems, Network Firewalls, Honeypots, Threat Intelligence Platforms, SIEM, and Behavior Analytics.
After establishing a threat detection system in the network, it will inspect all logs and traffic to and from the networks to identify the possible attacks. If a breach is detected, then the system will send an alert to the cybersecurity team.
How threat detection differs from threat hunting? Threat hunting is a proactive approach of searching and detecting cyber threats that are present undetected within the network. It is the process of finding malicious threat vectors that have escaped from the initial security analysis.
The major aim of threat prevention is to prevent a cyber incident that can cause damage to the business. Threat prevention activities provide a plan of action to implement security measures and stop the attack vectors to enter into the network. To prevent the organization from future attacks, it is mandatory to analyze the risks in advance and develop appropriate tactics. Prevention of network security can be accomplished by using various preventive measures such as using wireless routers, servers, firewalls, and other software tools. These preventive measures can recognize cyberattacks and block them from causing damage to the system.
Incident response is a planned approach to manage and respond to a cyberattack that can create havoc in enterprise security. The main goal of this approach to reduce the damage caused by data breaches and recover from them as soon as possible. An incident response plan will become effective only when the security team responds to the attack swiftly and prepare the business to defend against future threats.
The incident response plan consists of 6 phases such as preparation, identification, containment, eradication, recovery, and lessons learned. The preparation phase consists of advance planning to handle and prevent cyber incidents. In the second phase, potential attacks can be detected by monitoring and searching for any signs of a cyber threat. Containment strategy helps to identify and mitigate the risks by isolating the attack from other devices or networks. Once the issue is being isolated, the root cause of the attack will be eliminated in the eradication phase. Once the elimination process is done, the process of restoring the devices and systems will begin to bring back the business operations.
After executing the incident response plan, the security team members have to analyze and document the process involved in securing the organization. They have to understand the loopholes in the system and use the lessons learned to strengthen the network security to prevent future cyberattacks.
Having a strong and effective enterprise security management plan is crucial in today’s technological world where constant advancements are happening. An effective plan will help the organization to build a defensive approach against any kind of malicious attacks on the system. A well-trained and well-equipped cybersecurity team can implement the plan efficiently and support to resume the business operations quickly without wasting much time.
