為什么會出現數據庫可疑
Computer security is an issue that is not going to go away anytime soon, and any business that ignores cybersecurity does so at their peril. Whether it’s a data breach or the insertion of a piece of ransomware, you want to do everything you can to keep your computer networks safe.
計算機安全是一個不會很快消失的問題，任何忽略網絡安全的企業都將面臨危險。 無論是數據泄露還是插入勒索軟件，您都想盡一切努力確保計算機網絡安全。
Part of that involves being aware of what’s happening on your network and knowing how to recognize suspicious activity when it happens. By spotting trouble as soon as it appears, you stand a much better chance at saving yourself any number of headaches and costs.
其中一部分包括了解您的網絡上正在發生的事情，以及知道如何在可疑活動發生時對其進行識別。 通過盡快發現問題，您將有更多的機會節省許多麻煩和成本。
Here are some things to consider when it comes to identifying suspicious network activity.
在識別可疑網絡活動時，需要考慮以下事項。
識別可疑活動 (Identifying Suspicious Activity)
Any number of behaviors including database activities, unusual access patterns, and changes to files for logs can point toward a cyberattack or data breach. Recognizing these activities for what they are is vital if you want to locate the source and type of attack. Doing so will let you act quickly in stopping the security threat and minimizing any damage.
包括數據庫活動，異常訪問模式以及日志文件更改在內的許多行為都可能指向網絡攻擊或數據泄露。 如果您想找到攻擊的來源和類型，則必須認識到這些活動的重要性。 這樣做可以使您Swift采取行動，阻止安全威脅并最大程度地減少損害。
Here are some common examples of suspicious activity:
以下是一些可疑活動的常見示例：
Account abuse: The sudden overuse of privileged accounts to grant access to new or inactive accounts is a sure sign of an attack from the inside. Either an employee has initiated a run of unusual activity or a hacker has gained access to a top-tier account on your system. Other signs could include the sharing of information without cause, modifications applied to audit records, or mysterious deletion of login files.
帳戶濫用：特權帳戶突然被濫用以授予對新帳戶或非活動帳戶的訪問權限，這無疑是內部攻擊的跡象。 員工發起了一系列異常活動，或者黑客獲得了對您系統上頂級帳戶的訪問權限。 其他跡象可能包括無故共享信息，對審計記錄進行修改或神秘刪除登錄文件。
User access: Unexpected changes in user access are often a reliable sign that an outside hacker has acquired a user’s credentials and is poking around your system. Behaviors you may notice include user access at odd hours, remote access, and multiple failed attempts to log in.
用戶訪問權限：用戶訪問權限的意外更改通常是外部黑客已獲取用戶憑據并在您的系統中四處亂逛的可靠標志。 您可能會注意到的行為包括用戶在奇怪的時間訪問，遠程訪問以及多次嘗試登錄失敗。
Database activity: Unusual database activity can come from both inside and outside your business. Important signs to watch for include unexpected changes in users, changes in permissions, changes in data content growth, and access during non-business hours.
數據庫活動：異常的數據庫活動可能來自企業內部和外部。 要注意的重要標志包括用戶的意外更改，權限更改，數據內容增長的更改以及非工作時間的訪問。
Unexpected network behavior: Network activities that fall outside of usual expectations is a reliable signal that something amiss is happening. Look for traffic originating from outside your network, protocol violations, and unauthorized scans. A sudden change in network performance should also be checked out.
意外的網絡行為：超出正常預期的網絡活動是發生錯誤的可靠信號。 查找來自網絡外部的流量，協議違規和未經授權的掃描。 還應檢查網絡性能的突然變化。
Unexpected virus notifications and system slowdowns: Simple warnings to be on the lookout for would be a sudden increase in virus warnings or pop-up windows. If computers or networks slow to a crawl, there is a problem. A hacker may have gotten in and installed malicious software, or a website or email may have downloaded and installed bad software on the sly.
意外的病毒通知和系統速度降低：要監視的簡單警告可能是病毒警告或彈出窗口的突然增加。 如果計算機或網絡的爬網速度變慢，則存在問題。 黑客可能進入并安裝了惡意軟件，或者網站或電子郵件可能已經狡猾地下載并安裝了惡意軟件。
Unauthorized port access: Most ports have specific assignments. If unsanctioned port access occurs, it could be a sign that files are being accessed without authorization or that a malware attack is underway.
未經授權的端口訪問：大多數端口都有特定的分配。 如果發生未經批準的端口訪問，則可能表明未經授權訪問文件或正在進行惡意軟件攻擊。
可疑活動如何變化 (How Suspicious Activity Can Vary)
Depending on the sort of business you’re in, suspicious activity may present itself in different ways. For instance, smaller businesses might notice user abuse or abnormal database activities early on as a bad actor attempts to access personal or cardholder information. A larger business or financial institution may more likely experience dodgy account behavior, unauthorized port access, and malware or spyware designed to steal financial data and personal identity information.
根據您所從事的業務類型，可疑活動可能以不同的方式出現。 例如，較小的企業可能會在不良行為者嘗試訪問個人或持卡人信息時及早發現用戶濫用或數據庫活動異常。 規模較大的企業或金融機構可能更容易遇到狡猾的帳戶行為，未經授權的端口訪問以及旨在竊取金融數據和個人身份信息的惡意軟件或間諜軟件。
Some organizations find themselves the target of advanced persistent threats (APTs). These multi-phase attacks usually go after an organization’s network and vary in their subtlety as they poke and probe for weaknesses or backdoor access. APTs often choose to attack government organizations or large corporations but have been known to occasionally cause trouble for small and medium-sized businesses as well.
一些組織發現自己是高級持續威脅(APT)的目標。 這些多階段攻擊通常會跟蹤組織的網絡，并且在戳破和探查漏洞或后門訪問時，其細微程度會有所不同。 APT通常選擇攻擊政府組織或大型公司，但眾所周知，它們有時也會給中小型企業造成麻煩。
處理可疑的網絡活動 (Dealing With Suspicious Network Activity)
As with most security issues, the key to approaching suspicious network activity is prevention. This requires having set protocols and procedures for both you and your employees. An effective data security policy should include:
與大多數安全問題一樣，進行可疑網絡活動的關鍵是預防。 這需要為您和您的員工設置協議和程序。 有效的數據安全策略應包括：
- Solid password policies 可靠的密碼政策
- Periodic review of traffic, error reports, network alerts, and performance 定期檢查流量，錯誤報告，網絡警報和性能
- Malware and virus protection 惡意軟件和病毒防護
- Robust firewalls 強大的防火墻
- Regular risk assessments 定期風險評估
- Employee education 員工教育
- Incident and failure response strategies 事件和故障響應策略
- File integrity monitoring 文件完整性監控
使用文件完整性監視(FIM)保護數據 (Using File Integrity Monitoring (FIM) To Protect Your Data)
A big trend in cybersecurity as it related to data protection is something called file integrity Monitoring (FIM) as it allows you to automatically monitor networks, systems, and important files. With optimal FIM software, you can continuously scan and identify suspicious activity as it happens. This is an incredible boon if you’re the one responsible for a system’s security as you no longer have to look for a needle in a haystack. In this case, the needle is found for you and put you in a position before any lasting damage is done.
與數據保護相關的網絡安全大趨勢是文件完整性監控(FIM)，它使您可以自動監視網絡，系統和重要文件。 具有最佳FIM軟件 ，可以連續掃描和識別可疑的活動，因為它發生 。 如果您是負責系統安全性的人，那么這將是一個不可思議的福音，因為您不必再??為大海撈針了。 在這種情況下，將為您找到針頭并將您置于適當的位置，然后再進行任何持久的損壞。
Another plus with file integrity monitoring is that in addition to upping your data security strategy, it also helps you with the security standards needed for businesses and organizations that have regulatory compliance requirements such as HIPAA and PCI DSS.
文件完整性監控的另一個優點是，除了提高數據安全性策略之外，它還可以幫助您滿足具有法規遵從性要求的企業和組織(例如HIPAA和PCI DSS)所需的安全性標準。
Data security is a serious business. Your customers expect you to keep their information safe and your business’s reputation is on the line. As often as hackers and other bad actors keep finding new ways to target and exploit networks, so too do the strategies and tools for combating these threats evolve. Whether it’s adopting file integrity monitoring, conducting system activity audits, or running simple virus checkers, you can stay ahead. It just takes a bit of vigilance and commitment to your network’s security.
數據安全是一項嚴肅的業務。 您的客戶希望您保持其信息的安全，并且您的企業聲譽就高高在上。 隨著黑客和其他不良行為者不斷尋找針對和利用網絡的新方法，應對這些威脅的策略和工具也在不斷發展。 無論是采用文件完整性監視，進行系統活動審核或運行簡單的病毒檢查程序，您都可以保持領先地位。 它只需要對網絡的安全性保持警惕并做出一些承諾。
Your business will be stronger for it.
您的業??務將會因此而變得更強大。
