Certbar Security

Network security is a broad term that encompasses the policies, practices, and technologies used to protect the integrity, confidentiality, and availability of computer networks and data. Its primary goal is to safeguard the network infrastructure from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure, thereby ensuring the secure and continuous operation of an organization’s IT systems. Advantages of Network Security Protection Against Cyber Threats Advantage : Shields networks from malware, viruses, ransomware, and other malicious attacks. Disadvantage : Implementation and management can be complex and costly. Data Integrity and Confidentiality Advantage : Ensures that sensitive information is accessed only by authorized users and remains unaltered. Disadvantage : Encryption processes can sometimes slow down system performance. Regulatory Compliance Advantage : Helps organizations comply with laws and regulations such as GDPR, HIPAA, and PCI-

  1. Enhanced Security Posture Identifies vulnerabilities and weaknesses in the SAP environment. Provides recommendations for improving security controls. Enhances overall security measures, reducing the risk of breaches. 2. Compliance and Regulatory Adherence Ensures compliance with industry standards and regulations (e.g., GDPR, SOX). Helps meet internal and external audit requirements. Avoids legal penalties and fines associated with non-compliance. 3. Risk Mitigation Identifies and prioritizes security risks based on impact and likelihood. Implements risk mitigation strategies to protect critical assets. Reduces the potential for financial loss due to security incidents. 4. Improved Access Controls Evaluates user roles and authorizations to prevent excessive privileges. Enhances segregation of duties (SoD) to minimize the risk of fraud. Ensures that only authorized personnel have access to sensitive data. 5. Increased Operational Efficiency Identifies and resolves configuration iss
