&lt;blockquote&gt;
&lt;p&gt;&lt;strong&gt;Cyber Threat Intelligence)&lt;/strong&gt;&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;Cyber Threat Intelligence is when security experts collect and share clues about hackers — who they are, how they attack, and what they want — so everyone can defend themselves before an attack even happens.&lt;/p&gt;
&lt;h2 id="-like-a-neighborhood-watch-sharing-burglary-clues"&gt;🧩 Like a neighborhood watch sharing burglary clues&lt;/h2&gt;
&lt;p&gt;Imagine your street has been having break-ins. One neighbor notices muddy boot prints near their window, another spots a suspicious van parked outside, and a third sees their doorknob had been jiggled. They all share these clues at a neighborhood meeting and figure out it&amp;rsquo;s a crew that targets houses with broken porch lights on Tuesday nights. Now every neighbor knows to fix their porch light and double-lock the back door before Tuesday — and when the crew shows up, they find nothing easy to break into. Cyber Threat Intelligence works exactly like this: the neighborhood is the internet, the break-in crew is hackers, and the clues are digital footprints left behind in computer systems.&lt;/p&gt;</description></item></channel></rss>
