'''DEFCON''' (也写做 '''DEF CON,''' '''Defcon, or DC''') 是全球最大的计算机安全会议之一，自1993年6月起，每年在[[美国]][[内华达州]]的[[拉斯维加斯]]举办。 DEFCON的与会者主要有[[计算机安全]]领域的专家、[[记者]]、[[律师]]、政府雇员、安全研究员、学生和[[黑客]]等对安全领域有兴趣的成员，涉及的领域主要有软件安全、计算机架构、无线电窃听、硬件修改和其他容易受到攻击的信息领域。会议除了有对前沿技术的分享外，还有多种实践项目，如{{link-en|Wargames|Wargame (hacking)}}，最远距离 Wi-Fi 创建比赛，和计算机冷却系统比赛等等。

此外，大会还曾举办过其他活动，有些活动直到今天也在举办。如技术开锁比赛, Defcon机器人大赛，黑客艺术展，狂饮咖啡，寻宝游戏或[[奪旗 (網路安全)|夺旗赛]]（CTF）。在夺旗赛中，各支由计算机黑客组成的队伍使用专用软件及特殊的网络结构，对网络中的计算机进行攻防比赛。CTF比赛在很多其它的学术或军事技术会议中也被引入。

美国联邦执法部门如[[美国联邦调查局|联邦调查局]]，[[美国国防部]]，[[美国邮政检查局]]等，也常会有雇员参加活动。<ref name="Zetter" /><ref>{{cite web

== 历史 ==
DEFCON在1993年创立，最初只是{{link-en|Jeff Moss|Jeff Moss}}对一位老友的送别会。 <ref>{{Cite web|url=https://www.defcon.org/html/links/dc-about.html|title=DEF CON® Hacking Conference - About|last=Tangent|first=The Dark|website=www.defcon.org|access-date=2016-03-12|archive-date=2020-04-30|archive-url=https://web.archive.org/web/20200430153048/https://www.defcon.org/html/links/dc-about.html|dead-url=no}}</ref>这位朋友的父亲因为要赴海外工作，所以这位朋友也要离开美国。聚会本应在他离开的几天前在拉斯维加斯举办。然而，他的父亲提前出发，同时带走了这位朋友，所以Jeff策划的聚会缺失了重要的一部分。他索性邀请了他的所有黑客朋友，来拉斯维加斯参加这场聚会。一百多名朋友们不远万里赴会，而这场聚会也成为了DEFCON的基础。“DEFCON”一词来源于电影《[[戰爭遊戲 (1983年電影)|戰爭遊戲]]》（WarGames）中涉及的[[戒备状态|美国国家防卫等级（DEFCON）]]。在电影中，拉斯维加斯成为了核弹攻击的目标。而由于这次线下聚会也在这里举行，因此Jeff决定将其命名为“DEFCON”。 

DEFCON本来被计划为单次的聚会，但是Jeff不停的收到邮件，希望他明年也能举办一次同样的聚会。最终，他被人们说服，决定第二年再次举办DEFCON<ref>{{cite video | people = {{link-en|Jeff Moss (hacker)|Jeff Moss}} | date = 2007-07-30 | title = The Story of DEFCON | url = https://www.youtube.com/watch?v=lg6bQMTjHCE | accessdate = 2011-02-09 | archive-date = 2018-08-05 | archive-url = https://web.archive.org/web/20180805103821/https://www.youtube.com/watch?v=lg6bQMTjHCE | dead-url = no }}</ref>。在2016年，约有22,000人参与了DEFCON24。

=== 黑色纹章 ===
黑色纹章（'''Black Badge'''）实际是一块胸卡，这是DEFCON组委会对部分赛事的优胜者颁发的奖励。CTF比赛的优胜者和Hacker Jeopardy比赛的优胜者一般都能拿到这块牌子，但每年能够赢得这块胸卡的具体比赛列表并不相同。拥有这块胸卡，同时就拥有了DEFCON的终生免费参会权。<ref>{{Cite web|url=https://www.defcon.org/html/links/dc-black-badge.html|title=DEF CON® Hacking Conference - Black Badge Hall of Fame|last=Tangent|first=The Dark|website=www.defcon.org|access-date=2016-03-12|archive-date=2017-01-05|archive-url=https://web.archive.org/web/20170105034409/https://defcon.org/html/links/dc-black-badge.html|dead-url=no}}</ref>

2017年4月，一块黑色纹章在[[史密森尼学会]]的[[美国国家历史博物馆]]中作为展品被展出，题为“防御中的创新：人工智能和网络安全的挑战”<ref>{{Cite web|url=http://americanhistory.si.edu/innovations-defense|title=Innovations in Defense: Artificial Intelligence and the Challenge of Cybersecurity|website=americanhistory.si.edu|accessdate=2017-06-27|archive-date=2017-07-01|archive-url=https://web.archive.org/web/20170701005525/http://americanhistory.si.edu/innovations-defense|dead-url=no}}</ref>。这块纹章的拥有者，是ForAllSecure公司的“Mayhem网络推理系统”（Mayhem Cyber Reasoning System）<ref>{{Cite web|url=https://forallsecure.com/blog/2016/08/06/mayhem-wins-darpa-cgc/|title=Mayhem Wins DARPA CGC|accessdate=2017-06-27|archive-date=2019-02-15|archive-url=https://web.archive.org/web/20190215222729/https://forallsecure.com/blog/2016/08/06/mayhem-wins-darpa-cgc/|dead-url=no}}</ref>。这款程序在DEFCON24上的[[DARPA]] {{link-en|2016 Cyber Grand Challenge}}中赢得了冠军，是第一个赢得黑色纹章的非人类个体。

=== 会议筹款 ===
自DEFCON 11起，筹款工作由[[电子前哨基金会]]负责，第一次筹款活动是通过会议上的“官方”游戏{{link-en|Dunk Tank}}游戏完成的。目前，EFF每年会举办名为“The Summit”的聚会，主题有议题分享和资金募集。从2010年举办的DEFCON 18起，还会举办名为MohawkCon的筹款活动。
