Incident Response: The Best Practices

(Up)

When it comes to being ready for cyber attacks, you have to be prepared. It's like that old saying, "fail to prepare, prepare to fail" – that's real in the IT world.

IBM says you could save like $2 million if you have a skilled team and do some testing. And Secureworks says you have to keep updating your strategies to match the latest threats.

You have to follow frameworks from NIST and SANS, like CrowdStrike says, and put together a cross-functional team.

You need a solid incident response plan (IRP) that lays out who does what, so everyone knows their role and can act fast.

For detecting attacks, you need real-time monitoring to spot any unusual activity or known threats.

TechTarget talks about different detection frameworks like ISACA and ISO, and over 70% of breaches are spotted from outside the company, according to Atlassian.

AI and machine learning can help you catch anomalies and known threats better, so you stay one step ahead of the hackers.

When it comes to containing the attack, you have to act fast.

You might need to disconnect systems right away or change access controls, depending on the situation. NIST says you should segment your network to limit the damage.

Secureworks talks about this "Integrated Preparedness Cycle" where you learn from each incident and keep improving your containment strategies.

And don't forget about removing the malware and restoring your systems.

SANS Institute has a multi-step approach to make sure you get rid of every trace of the threat and fix any weaknesses that let the hackers in. But SecurityScorecard says you have to double-check everything before restoring your systems, so you don't get hit again and can keep running your business smoothly.

Incident Recovery: The Best Practices

(Up)

Let me break it down for you real quick. When some sh*t goes down and your systems get hit, you gotta bounce back fast to keep your biz running smooth.

Most crews, like 71% of 'em, got a recovery plan locked and loaded.

This bad boy lays out all the steps to get your critical systems back online and your data restored from secure backups. It's like a cheat code for dealing with cyber attacks and ransomware, courtesy of the big dogs at CISA.

  • First up, you gotta assess the damage and figure out which areas need the most love.
  • Then, you follow the step-by-step guide to resurrect your systems and networks, with some expert advice from the industry peeps.
  • Finally, you gotta double-check that everything's running smoothly after the restoration, and keep those logs safe for future reference.

Data recovery is a whole other ball game, though.

43% of companies have had to deal with data loss, which can really mess up your flow. Here's the play:

  1. Backup, backup, backup! Keep encrypted copies in different locations to avoid losing your precious data. And don't forget to patch those backup apps.
  2. Use legit recovery software that knows its stuff, and make sure those backups are clean before you restore 'em.
  3. Practice makes perfect, so run some recovery drills to stay sharp. The NCSC's got your back with tips on dealing with malware and ransomware.

But prevention is key, right? 58% of organizations that keep a watchful eye on their systems can spot trouble almost instantly, minimizing the damage.

Here's how you do it:

  • Monitor your network traffic and behavior like a hawk, following the security guidelines from AWS.
  • Set up alerts to ping your IT squad when something's fishy, so they can jump on it right away.
  • Keep updating and patching your systems, because those cyber threats ain't playin' around.

Look, 84% of businesses know continuous monitoring is a must these days, but not everyone's got the tools to make it happen.

As one expert puts it,

"Continuous monitoring ain't no luxury. It's a necessity if you want your biz to survive in this digital jungle."

Case Study: Successful Incident Response and Recovery

The 2017 Equifax data breach was a total shitshow, but they got their act together quick. Once they realized over 147 million people's info got jacked, they locked that shit down and started the cleanup.

  • Investigation Mode: They hired these cybersecurity ninjas from Mandiant to dig deep and figure out what went down. Took 'em 60 days to map out the whole mess.
  • Protecting the Peeps: Equifax hooked up the folks affected with free credit monitoring, so their identities didn't get snatched.
  • Tightening Security: They leveled up their encryption game to keep that data on lockdown.

Equifax dropped a cool $1.25 billion to beef up their security.

Word on the street is, they've been locking it down since then. IT nerds have been taking notes on how they handled the situation – getting on that shit fast, making moves, and keeping it real with the public.

Even some Gartner analyst gave 'em props for their incident management skills.

Other companies have their own ways of dealing with breaches too. Google's got this Incident Command System that helps them scale up and manage shit effectively.

Then there's this financial company that shared their story on LinkedIn, talking about how crucial their Security Operations Center (SOC) is for fighting off cyber threats.

And Cisco Talos? They emphasized how having solid partners makes a huge difference in responding quickly and effectively.

Equifax's recovery game, combined with the wisdom from other firms, shows how following best practices can minimize damage and rebuild trust.

Their story, along with the other case studies, drives home the importance of having a tight incident response strategy. Companies need to stay on top of their game to keep their rep intact and protect their people.
