商品描述
Description:
Intrusion detection is not for the faint at heart. But, if you are a network administrator chances are you're under increasing pressure to ensure that mission-critical systems are safe--in fact impenetrable--from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders.
Designing a reliable way to detect intruders before they get in is a vital but daunting challenge. Because of this, a plethora of complex, sophisticated, and pricy software solutions are now available. In terms of raw power and features, SNORT, the most commonly used Open Source Intrusion Detection System, (IDS) has begun to eclipse many expensive proprietary IDSes. In terms of documentation or ease of use, however, SNORT can seem overwhelming. Which output plugin to use? How do you to email alerts to yourself? Most importantly, how do you sort through the immense amount of information Snort makes available to you?
Many intrusion detection books are long on theory but short on specifics and practical examples. Not Managing Security with Snort and IDS Tools. This new book is a thorough, exceptionally practical guide to managing network security using Snort 2.1 (the latest release) and dozens of other high-quality open source other open source intrusion detection programs.
Managing Security with Snort and IDS Tools covers reliable methods for detecting network intruders, from using simple packet sniffers to more sophisticated IDS (Intrusion Detection Systems) applications and the GUI interfaces for managing them. A comprehensive but concise guide for monitoring illegal entry attempts, this invaluable new book explains how to shut down and secure workstations, servers, firewalls, routers, sensors and other network devices.
Step-by-step instructions are provided to quickly get up and running with Snort. Each chapter includes links for the programs discussed, and additional links at the end of the book give administrators access to numerous web sites for additional information and instructional material that will satisfy even the most serious security enthusiasts.
Managing Security with Snort and IDS Tools maps out a proactive--and effective--approach to keeping your systems safe from attack.

**描述:**
入侵檢測並不適合心臟不夠強健的人。但如果你是一名網路管理員,你可能面臨越來越大的壓力,必須確保任務關鍵系統的安全——事實上是無法穿透的——免受惡意程式碼、緩衝區溢位、隱形端口掃描、SMB 探測、作業系統指紋識別嘗試、CGI 攻擊及其他網路入侵者的威脅。
設計一種可靠的方法來在入侵者進入之前檢測他們是一項至關重要但艱巨的挑戰。因此,現在有大量複雜、精密且價格不菲的軟體解決方案可供選擇。在原始性能和功能方面,SNORT,最常用的開源入侵檢測系統(IDS),已開始超越許多昂貴的專有 IDS。然而,在文檔或易用性方面,SNORT 可能會讓人感到不知所措。應該使用哪個輸出插件?如何將警報通過電子郵件發送給自己?最重要的是,如何篩選 SNORT 提供的大量資訊?
許多入侵檢測書籍在理論上長篇大論,但在具體和實用範例上卻顯得不足。《Managing Security with Snort and IDS Tools》則不然。這本新書是一本全面且極具實用性的指南,旨在使用 SNORT 2.1(最新版本)及其他數十個高品質開源入侵檢測程式來管理網路安全。
《Managing Security with Snort and IDS Tools》涵蓋了檢測網路入侵者的可靠方法,從使用簡單的封包嗅探器到更複雜的 IDS 應用程式及其管理的 GUI 介面。這本寶貴的新書是監控非法入侵嘗試的全面但簡明的指南,解釋了如何關閉和保護工作站、伺服器、防火牆、路由器、感測器及其他網路設備。
提供逐步指導,讓你能快速啟動並運行 SNORT。每章都包含所討論程式的連結,書末的附加連結則為管理員提供了訪問眾多網站的途徑,以獲取更多資訊和教學材料,滿足即使是最嚴肅的安全愛好者的需求。
《Managing Security with Snort and IDS Tools》規劃出一種主動且有效的方法,以保護你的系統免受攻擊。
