Oracle Security: Essential Techniques to Keep Your Data Safe

Oracle databases are integral to modern technology infrastructure, providing many companies with an online data storage option and transaction capabilities. Because databases contain such sensitive or essential information about an organization, hackers and cyber attackers often view them as tempting targets - leading them to breach databases resulting in expensive breaches and cyberattacks that cost organizations even more money than anticipated. For this reason, organizations should take all possible precautions in protecting their databases against breaches.

Your database systems should be managed and configured to reduce security risks, and this post will explore Oracle Database Security Best Practices and Solutions. Oracle Hardening involves safeguarding and protecting the contents of your database server.

Data Security - Defining

Database security refers to any measures to secure information from unapproved access and ensure its confidentiality, integrity, and availability. Effective data protection techniques include data encryption, key management, redaction/subsetting techniques, and masking/masking techniques - among others - auditing/monitoring procedures may also be taken. cloud services, insider threats,

Data Security Is Essential

Data is a vital resource for any business, making its protection an absolute priority. Failure to adhere to regulations, perform audits or comply with data breaches may damage an organization's reputation.

Financial losses can occur as fines can reach as much as four percent of an organization's annual global revenue under the General Data Protection Regulation of European Union (GDPR) fines imposed for breaches; breaches can even incur fines of four percent of annual global revenue which often results in significant financial losses due to breaches affecting personally identifiable information, finances, health information or intellectual property that need protecting to achieve compliance and prevent breaches arising - protecting it is vital ensuring compliance!

Oracle Database Security PracticesUse A Password That Is Not Default

Eliminating default passwords is a straightforward step you can take toward increasing Oracle security controls. Hackers take advantage of passwords that are easily compromised or brute-force decoded using brute-force attacks, using brute force as their technique of choice to gain entry or harm databases. 

Assuming you were an attacker looking for access or harming MySQL databases misconfigured for the attack, changing weak default or weak passwords with more complex ones would likely have the most significant effect. Oracle Secure External Password Store makes this task straightforward. It offers wallet storage of credentials securely encrypted under its encrypted vault for credential storage needs.

Oracle Database includes tools that help ensure password safety, but some may be turned off by default; to maximize protection, make sure to enable them for maximum safety. One such tool is checked, a password cracker that compares local password hashes against an extensive dictionary to identify accounts with weak passwords; SQL scripts can help determine if any accounts still use default passwords.

Password Verification is another feature available within Oracle Database that is usually turned off by default but can be activated by logging into SQL*Plus as an administrator and initiating the appropriate scripts to verify passwords. You can even adjust its requirements according to your IT department's needs.

Patch Early, Patch Often

Maintaining strong Oracle database standards involves updating software and applications as part of a successful maintenance program. Patching is just as essential as installing the latest version of the Oracle Database Management System or keeping the host operating system current.

Oracle delivers Critical Patch Updates in January, April, and July four times yearly. These patches include fixes for Oracle products (Java security updates) and details on vulnerabilities addressed by these patches - unknowingly leading hackers to exploit the weaknesses they identify if organizations delay applying patches to their Oracle databases. 

According to Wallarm's State of Network Security Report, hackers have exploited these weaknesses within two hours if organizations do not apply patches quickly enough. Therefore advanced security professionals suggest applying patches immediately; Oracle offers a website to view alerts and plan for scheduled updates!

Limit User Privileges

Only sometimes accurate in data security terms is that asking for forgiveness rather than permission is always best. Preventing security breaches rather than trying to repair them is preferable, as preventing users from accessing tools or database applications they do not require and adding, editing, or deleting information without authorization in your database.

Administrators would do well to seek the cooperation of users rather than give them excessive privileges that could lead to malicious acts. Conducting reviews of user privileges, revising as necessary, and revoking them if needed are essential steps toward protecting sensitive data from gaining unauthorized access.

Audit Your Database Regularly

Regular database audits are another best practice to help protect sensitive data. Oracle's audit trail helps detect and resolve security threats by keeping an audit log of all changes made to your database's roles, objects, or permissions - including successful and unsuccessful logon attempts that might indicate someone is conducting brute force attacks against it.

As explained later, applications can provide the ideal way to audit database activity in an ideal world. A good software solution should collect and correlate logs for central auditing; this streamlines the report generation process and may reveal long-term trends hidden through more detailed analysis.

Implement Strong Authentication Methods

An effective authentication system is vital to maintaining security best practices in distributed environments such as Oracle Database. Oracle can be configured to support third-party authentication protocols like Kerberos (also known as Secure Sockets Layer or SSL) and Remote Authentication dial-in user service (RADIUS), industry-standard methods used to protect database connections and access.

Integrating one of these authentication options into your Oracle setup helps protect against malicious actors while guaranteeing that only authorized people gain entry.

Use Additional Security Tools To Manage Sensitive Data

Breach of data can be devastatingly costly to an organization's reputation and bottom line, as well as to individuals whose personal information resides within its database. To safeguard such sensitive information, personal data relating to health conditions, intellectual property rights, or payment details must be carefully treated.

Oracle Database includes transparent Sensitive Data Protection that enables you to easily classify and search table columns containing sensitive data (such as Social Security Numbers or credit card numbers) and create policies designed to secure this sensitive information.

Although free tools can be beneficial, they sometimes offer different protection and monitoring than paid options. An application toolkit could help expedite maintaining Oracle security standards more efficiently if you can afford database monitoring tools. In contrast, database activity monitoring software enables you to monitor changes within your database.

Oracle Advanced Security is a paid upgrade that includes tools for monitoring database activity and a data encryption program to encrypt text data into unintelligible code requiring an algorithmic key for decipherment - making it exceedingly difficult for anyone to decrypt text data.

Best Oracle Database Security Solutions

Third-party oracle solution providers can add an extra level of insight. SolarWinds' Database Performance Analyzer and Security Event Manager are particularly helpful in keeping my systems safe. You'll have access to an assortment of features and tools - many automatic - which make monitoring security measures much less tedious.

• Database Performance Analyzer: Database Performance Analyzer employs anomaly detection protocols that will notify you if the behavior of your database differs from expected, which could indicate suspicious or unauthorized activity. The application also learns the typical patterns associated with your databases while employing a lightweight monitoring system that won't impact load times.

• Security Event Manager: Security Event Manager integrates both SIM and SEM protocols, enabling it to monitor network activity in real-time and via historical logs in real-time and log format, respectively. 

It allows it to identify patterns of long-term suspicious or unauthorized behavior, detect intrusions as they happen, and customize the auditing of an Oracle database if desired. Security Event Manager tracks all database changes, from logins and logouts to configuration modifications. It integrates seamlessly with Oracle Database, offering a script called "Recommended Oracle Audit," which monitors these categories and others.

• Patch Manager: SolarWinds (r) Patch Manager is an invaluable tool enabling administrators to efficiently administer third-party patches across thousands of workstations and servers simultaneously. Patch Manager reduces patch deployment time from weeks to minutes using pre-built, tested patches designed to ensure successful deployments for essential business apps such as Adobe, Apple, and Oracle.

• Database Firewalls: Database firewalls offer further protection for your database. Firewalls act as proxy servers to authorize and secure traffic coming in and out while also helping prevent SQL Injection attacks from successfully taking place.

Educate Your End Users

Studies reveal an alarming rise in cybercrime, and attacks often target individuals rather than systems. Even with top firewalls and SIEM software, user-generated security issues may wiggle through. 

If someone with administrative rights in your company keeps leaving sticky notes around - for example, on monitors, keyboards, or any other prominent places - this increases the chances that someone malicious will do something harmful.

Regular security training for end users can be an effective way to reinforce the importance of precaution. Support technicians and DBAs can inform workers about security standards, legislation, and cybercrime trends.

Stay Vigilant

Unfortunately, database security is an ongoing and constant process; there's no "one and done" model. With data being such an essential resource in today's information age and cyber attackers becoming ever more determined to breach it, complacency should always be taken seriously regarding security - any time taken away is likely an attack waiting to happen! 

To protect yourself adequately and your database from potential hackers, it's essential that Oracle security standards remain up-to-date and enforced - this will go a long way toward keeping hackers at bay!

The battle can seem long and tiring as we rarely hear of IT departments that successfully defend against cyberattacks. Yet no news may be good in many instances - as it shows your data is protected adequately.

Conclusion

Any data management system must seek to ensure data security, particularly protection from unauthorized access. Information security has become of utmost importance.

Well-organized institutions typically maintain databases containing various information relevant to various circumstances. We have proposed an easy method for improving database security that remains effective despite its simplicity.
