File Server auditing lets the auditor to trace the secrets hidden beneath the walls of logs. This gives a precise and clear idea who had exactly accessed a file/folder, what changes s/he had made, when, and from where. In addition, the in-depth auditing lets the auditor create the long trails of any change and give an idea about its impact in the future. Not only they can prepare an action plan to revert the undesired changes but they also get equipped to notify and fight with the unauthorized access to the file server. In this post, we’ll discuss the benefits of auditing a file server and the ways to start it on a normal desktop and a Windows Server. Benefits of File Server Auditing Bringing out the secrets File Server logs clearly reveals the access of the users and the changes they’ve made while using the files and folders. This will strengthen them to prove the charges levied against a user for deleting an important file, accessing cryptographic key file meant for account information, or modifying a document. Highlighting the intrusion The auditor can crosscheck the accesses/changes to the file servers at different moments and highlights the unauthorized access. Such an access can be made inside and outside the organization. Keeping an eye on the system files gives an idea about the virus or malware attacks as well. Securing the System Getting the information on time regarding an unauthorized change or a malicious access to the system files, the administrators can take precautionary steps from saving the file server from unwanted situations. Using PowerShell and CMDlets, they can generate the reports manually to highlight such undesired changes and take preventive steps to avoid any kind of irreparable loss.

This will display the following dialog box to select a user, computer or group. Figure: “Select User, Computer or Group” dialog box 4. Enter the name of users that you want to monitor and click “Check Names” button. 5. Once you’re done then click “OK” button. This will show the following dialog box. Figure: Auditing dialog box 6. Select all the access attributes and their both values “Successful” and “Failed”. 7. Select “Apply these auditing entries to objects and/or containers within this container only”. 8. Click “OK” button. Conclusion File Server Auditing helps a lot in identifying the accesses to the files and let the auditor to highlight the intrusions, if any. In addition, it’s quite simple to follow the above mentioned steps to enable the auditing on the Windows machines.
Digital forensics can be broken down into three phases; acquisition, analysis, and presentation. The acquisition phase is where the data is saved in a way that it can be analyzed latter. Because it is not known at the time what data is or is not valuable to the case, all data is saved. In the analysis phase, the data is examined and placed into three major categories; inculpatory, exculpatory, or signs of evidence tampering (Carrier, 2002). Tools are used in this phase that are able to analyze for the list directory contents, deleted files, and recover the deleted files. In the presentation phase, the data has been documented in a way that it can undergo a peer review. When deleted files are recovered, the analyst must show how they were found because they were ...
The analysis will allow the NIDS to alert on activity which could be a sign of unauthorized access or malicious activity. The IT security team will check the alerts to determine if an event or incident has occurred. Similarly, an HIDS application will be installed on all servers and workstations. The HIDS application will analyze the servers and workstation and check the system logs to determine if any potential unauthorized or malicious activity has occurred and send the information to the NIDS for processing and alert creation.
Every piece of information must be traceable back to the data input that produced it. The main action of audit trail is captures a sources of all data items at the time of getting entrance into the system. The other constituent of input control and security involves data security rules and measures to protect data from being or lost or damaged. The records retention policy is the practice of storing documents in a safe location and making sure to see to legal requirements or business needs. Input security and control also involves the process of encrypting or encryption of data so only users with the code it software can read
Investigators must ensure the integrity of all evidence collected, analyzed, processed and presented to a courtroom and jury. The reason that this is important is because the improper collection and analysis of evidence can lead to compromised data and potential damage to a prosecution. The seizure and analysis of digital evidence can be particularly challenging but is just as critical to a case as physical evidence. There are specific procedures that must be met to ensure the successful collection and analysis of digital media and guidelines or best practices for collection of all evidence, both physical and digital that must be followed. Conducting the proper steps in an investigation regarding the collection and processing of evidence and the proper chain of custody requirements can ensure a successful outcome in solving a case and a successful prosecution.
Nowadays, most of the web, email, database and fileservers are Linux servers. Linux is a UNIX system which implies that it has solid compatibility, stability and security features. Linux is used for the mentioned environments because these services require high security. Further, an increase of attacks on these servers can be observed. Additionally, the methods to prevent intrusions on Linux machines are insufficient. Further, the analysis of incidents on Linux systems are not considered appropriately (Choi, Savoldi, Gubian, Lee, & Lee, 2008). It can also be observed that a lot of investigators do not have experience with Linux forensics (Altheide, 2004).
Real-time access to log data will allow you to filter and locate event that could be the cause of a security breach.
30 Privacy Rights Clearinghouse (2002) Employee Monitoring: Is There Privacy in the Workplace? . (6/3/2004)
One type of surveillance is employee monitoring. Many employers monitor their workers’ activities for one reason or another. Companies monitor employees using many methods. They may use access panels that requires employees to identify themselves to control entry to various area in the building, allowing them to create a log of employee movements. They may also use software to monitor attendance and work hours. Additionally, many programs allows companies to monitor activities performed on work computers, inspect employee emails, log keystrokes, etc. An emerging methods of employee monitor also include social network and search engine monitoring. Employers can find out who their employees are associated with, as well as other potentially incriminating information. (Ciocchetti)
When we are using the company’s network, phone or laptop/desktop then we are utilizing company resources so there is no entitlement to 100% privacy even if it is something we are doing outside of our normal job. Employee monitoring has become the standard for most if not all corporations today in a wide range of occupations. In order to manage the
When someone suspects that an unauthorized, unacceptable, or unlawful event has occurred involving an organization’s computer networks or data-processing equipment Computer security incidents are normally identified. Initially, the incident may be reported by an ultimate user, detected by a system administrator, identified by IDS alerts, or discovered
...t to track all Internal and External users activity, auditing plays the key role in monitoring these user actions. Data masking and encryption technology provide certain level of assurance that data is not easily accessible to unauthorized users.
Audit Risk is the risk that an auditor has stated an incorrect audit opinion on the financial statements. It may cause the auditors fail to alter the opinion when the financial statements contain material misstatement. The auditor should perform the audit to lower the audit risk to a sufficiently low level. In the auditor’s professional judgement, the auditor should appropriately state a correct opinion on the financial statement
Auditing has been the backbone of the complicated business world and has always changed with the times. As the business world grew strong, auditors’ roles grew more important. The auditors’ job became more difficult as the accounting principles changed. It also became easier with the use of internal controls, which introduced the need for testing, not a complete audit. Scandals and stock market crashes made auditors aware of deficiencies in auditing, and the auditing community was always quick to fix those deficiencies. Computers played an important role of changing the way audits were performed and also brought along some difficulties.
Overall, the company is having ineffective controls regarding different departments and in the whole organization. An effective internal audit department should be established within the organization which should test the effectiveness of these controls on regular basis and make it sure that all controls are working effectively and efficiently with the different departments of the organization. Also the Internal auditor should implement the most effective processes and measures to prevent and detect the fraud, corruption and non compliance with the laws and regulations in the organization. Establishment of internal audit committee would be helpful in this regard which comprises of executive and non executive directors.
No matter auditors work with technology or not, the most important thing in process of auditing is evidence. The basic framework for the auditor understands of evidence and its use to support the auditor's opinion on the financial statement. In reaching an opinion on the financial statements, the evidence gathered from the audit procedure is used to determine the fairness of the financial statements and the type of audit report to be issued. The characters of paper audit evidence are:
