The Best Network Security Auditing Tools

Best Network Security Auditing Tools

Stephen Cooper

A vulnerability in your network will leave your entire business exposed to threats. You need to audit your network security.

You know you need network security but how do you know that it’s good enough? How do you know that secure working practices are being followed and all of your security settings are protected against tampering? You need to check your network security systems constantly. You also need to assess the efficacy of those systems periodically.

Network security auditing provides those periodic assessments and it has two aspects: potential vulnerability and historic performance. Data protection standards demand security auditing, not only to ensure that the strongest security is in place but also to identify whether successful attacks have taken place.

Here is our list of the nine best network security auditing tools:

  1. SolarWinds Access Rights Manager – FREE TRIAL An access control system that helps protect the user accounts and device access. This tool also includes extensive network and system auditing tools.  It runs on Windows Server.
  2. ManageEngine ADAudit Plus Analyze user access accounts, log user activity, and audit the system for data security standards. It runs on Windows Server.
  3. PaperTrail A cloud-based log manager and audit archiving service that includes data searching and analysis features.
  4. LogicGate A cloud-based IT governance, risk assessment, and security standards auditing tool.
  5. Splunk Enterprise Security A network security system that includes incident response auditing and standards compliance auditing.
  6. Intruder.io A cloud-based monthly vulnerability scanner with an on-demand scanning function, software inventory analysis, and the services of a pen-testing team.
  7. Netwrix Auditor A network security auditing tool that includes configuration management and protection. It installs on Windows and Windows Server.
  8. Acunetix A suite of software testing tools that focus on the vulnerabilities in Web applications. It is available for Windows, macOS, and Linux.
  9. Nessus A vulnerability assessment tool in free and paid versions that includes auditing reports. It is available for Windows, macOS, and Linux.

Data security standards bodies don’t blacklist businesses that have been hit by an intruder and suffered data disclosure. This is because the unlucky business that is the first to be the victim of a new attack strategy can’t be blamed for the unpreparedness of all cybersecurity systems in the world. In these cases, the victimized business is expected to admit the security breach and inform all of those individuals and businesses whose data has been compromised.

The knowledge that auditing requirements are eventually going to reveal any security breach drives the demand for businesses to spot successful attacks as quickly as possible and implement mitigation procedures – even though the data leak has already occurred.

So, there is a close link between network security systems and network security auditing tools. While network security processes survey the network, they simultaneously record all conditions on the network second by second, laying down the necessary data stores that network security auditing needs. When you look into network security auditing tools, you also need to consider the audit-related features of network security systems.

The best network security auditing tools

You can read more about each of these options in the following sections.

1. SolarWinds Access Rights Manager – FREE TRIAL

access rights manager solarwinds

The SolarWinds Access Rights Manager gives you an interface to Active Directory (AD), SharePoint, and Exchange Server. These three services can have many implementations within one company and the access rights systems operating on different sites or for different departments might need to be unified or kept separate, according to the business’s security policy. The complexities of different access rights strategies can be difficult to manage, so a specialist tool, such as this can help you track and control access rights more effectively.

While letting you coordinate issues such as replication and backup, the Access Rights Manager also lays down data sources for network security auditing. As well as logging all actions taken within the AD environment, it stores records of user account activity and device access events. These activity log messages are all timestamped. This enables you to quickly trace through and see which account was accessing which resource at the time that a security incident took place.

The log files that the Access Rights Manager creates are useful both for internal network security auditing and for external audits. These records need to be archived over a long period for access by compliance auditors. Implementing a log archiving strategy for these Access Rights Manager records will enable you to demonstrate compliance with GDPR, PCI-DSS, HIPAA, and other data security standards – passing any standards audit with ease.

The SolarWinds Access Rights Manager runs on Windows Server and it is available for a 30-day free trial.

2. ManageEngine ADAudit Plus

ManageEngine ADAudit Plus

ManageEngine ADAudit Plus is a specialized auditing system for access rights management issues. This ManageEngine software package assists towards compliance reporting for a number of data security standards, such as GDPR, HIPAA, and PCI DSS.

The main purpose of this tool is to log all security-related events that occur on the network with respect to user accounts and resource access. It tracks logon failures, changes to user accounts and resource permissions, and alterations to the settings of Active Directory instances. It monitors AD implementations for SharePoint and Exchange Server as well as Windows user accounts systems.

As well as generating log files for auditing use, this service protects those files from tampering. It also monitors and protects the permissions of the folders that contain AD audit log files. These measures, together with the monitoring of accounts and settings within AD, block attempts by intruders to hide their presence.

The ADAudit Plus system includes logfile management services that create archives of older directories. These archives can be stored for up to three years and it is possible to bring them back to current availability in the event that they are needed for an external standards compliance audit. The system also includes report formats and query templates that are tailored to a range of network security auditing requirements, including those needed for standards compliance reporting.

ManageEngine ADAudit Plus installs on Windows and is available in four editions. The lowest of these options is Free – this has limited capabilities. The three full versions are the Trial edition, which is active for 30 days, the Standard Edition, and the Professional Edition.

3. PaperTrail

PaperTrail

PaperTrail is a log management service that is particularly useful for those who need to store and archive network security logs for auditing purposes. This system will store log messages from a range of applications and also gather Windows Event logs and Syslog messages. The management of these records is essential for your network security auditing strategy.

Log messages get collected by PaperTrail agents, which need to be installed on your servers. These messages are then uploaded to the PaperTrail server for processing. The first thing the log manager does with these messages is to convert them into a neutral format so that they can be stored in the same location. This unifying step also makes it possible to search through one source of data when analyzing log messages for signs of a security breach. The PaperTrail dashboard includes a viewer that enables you to load in log messages for analysis.

PaperTrail includes an archiving mechanism that can revive those files, and bring them back into a live status when required for external audits. This is an essential service for compliance auditing.

The data processing and storage capacity and file availability period are dictated by the plan each customer chooses. The service is charged by subscription with a monthly fee. There are six editions available and the first of these is Free – which has an initial throughput allowance of 16 GB, which is topped up by 50 MB per month. The five paid plans have successively larger data allowances.
