Key Discussion Points & Insights

1. Defining CIRT / CERT

• Definition & Scope

  • CIRT: "A team responsible for responding to and managing cybersecurity incidents involving computer systems and networks in order to minimize the damage and to restore normal operations as quickly as possible." [01:03]
  • Example: “The CERT worked to break the intrusion kill chain of the scattered spider attack campaign.” [01:18]

• CIRT vs. CERT vs. SOC

  • CERT (with an E): Coordinates incident response for a community (e.g., a country or industry sector).
  • CIRT (with an I): Coordinates response within a single organization, bringing together IT, legal, PR, etc.
  • SOC (Security Operations Center): Central location within an organization where security analysts monitor and respond to security events.
  • “In some cases, security pundits use the terms interchangeably. In general, though, a CERT with an E coordinates incident response for a community or like a specific country or industry sector, a CERT with an I coordinates incident response across multiple functions within one organization.” [01:35]

2. Historical Origin

• The Morris Worm (1988):
  • First major internet worm, created by Robert Tappan Morris.
  • Impacted roughly 10% of the existing Internet at the time.
  • Resulted in the first felony conviction under the 1986 Computer Fraud and Abuse Act.
  • Prompted DARPA to fund the first CERT (with an E) Coordination Center at Carnegie Mellon University.
  • “The idea of a centralized incident response team began in the aftermath of the famous Morris worm of 1988.” [02:08]

3. Pop Culture Reference: TV Show "24"

• Depiction of CERT in Media:
  • Reference to the show "24" (2001-2010), where Chloe O’Brien manages tech for Counterterrorism agent Jack Bauer.
  • Early use of branded security technology in mainstream entertainment, specifically Cisco’s Security Response system.
  • “Back in the CERT with an I, Chloe O'Brien…manages the tech within the operations center.” [03:04]

Memorable Dialogue (from "24")

• Network Attack Identified:
  • [04:13]
    • D: “How did this happen? Mr. Buchanan? The network security module lit up. Someone on the outside is trying to jam our satellite servers.”
  • [04:25]
    • E: “Could this just be a high network load?”
  • [04:27]
    • D: “No, it's definitely denial of service attempt. What do you want me to do?”
  • [04:32]
    • D: “No, the Cisco system is self-defending.”
  • [04:35]
    • C (narrator): “Did you catch that? Chloe said that there is no damage yet because the Cisco system is self defending. How cool is that?” [04:36]

4. Cybersecurity Product Placement

• Cisco’s Four-Time Product Mention:
  • The episode highlights Cisco’s skilled product placement within the "24" scene, emphasizing the self-defending nature of its systems and the ease with which fictional CERT teams use them.
  • “And for those keeping score, in just under 45 seconds, Cisco had their product mentioned on four separate occasions. Brilliant.” [04:53]

Notable Quotes & Moments with Timestamps

• On the Difference Between CERT and CIRT:
  • “A CERT with an E coordinates incident response for a community… A CERT with an I coordinates incident response across multiple functions within one organization.” [01:35]
• On the First Ever CERT:
  • “The idea of a centralized incident Response team began in the aftermath of the famous Morris worm of 1988.” [02:08]
• On Fictional CIRT Operations:
  • “Chloe said that there is no damage yet because the Cisco system is self defending. How cool is that?” [04:36]
  • “Did you catch that too? Chloe's boss just told her to use the Cisco auditing tool. And for those keeping score, in just under 45 seconds, Cisco had their product mentioned on four separate occasions. Brilliant.” [04:53]

The word is cert. Spelled C for cyber, I for incident, R for response and T for teams. Definition A team responsible for responding to and managing cybersecurity incidents involving computer systems and networks in order to minimize the damage and to restore normal operations as quickly as possible. Example Sentence the CERT worked to break the intrusion kill chain of the scattered spider attack campaign. Origin and Context A Cyber Incident Response Team CERT with an I is similar to a Computer Emergency Response Team cert with an E and a Security Operations center or sar. In some cases, security pundits use the terms interchangeably. In general, though, a CERT with an E coordinates incident response for a community or like a specific country or industry sector, a CERT with an I coordinates incident response across multiple functions within one organization. Like IT legal and public relations, a SOC is a central location within an organization where a group of security analysts monitor and respond to security related data from many different sources. The idea of a centralized incident Response team began in the aftermath of the famous Morse worm of 1988. A first year computer science graduate student at Cornell University, Robert Tappan Morris, created and launched the worm. It was the first of its kind to cause as much damage as it did by impacting 10% of the existing Internet. It also resulted in the first felony conviction in the US under the 1986 Computer Fraud and Abuse act and prompted DARPA, the defense advanced Research Projects Agency, to fund the establishment of the CERT with an E coordination center at Carnegie Mellon University. Nerd Reference on the Fox TV show 24 that ran from 2001 to 2010, counterterrorism agent Jack Bauer, played by Kiefer Sutherland, races against the clock to subvert terrorist plots. Back in the Cert with an Eye, Chloe o', Brien, played by Mary Lynn Rhys Cub, manages the tech within the operations center. Back in those security vendor Cisco was famous for placing its products on TV shows and movies. This scene opens with a shot of the Cisco product Security Response system showing on one of the operating system monitors. Its alert is that there is a network traffic spike.

[D]

How did this happen? Mr. Buchanan? The network security module lit up. Someone on the outside is trying to jam our satellite servers.

[E]

Could this just be a high network load?

[D]

No, it's definitely denial of service attempt. What do you want me to do?

[E]

To do any damage yet?

[D]

No, the Cisco system is self defending.

[E]

All right, have one of your people.

[C]

Did you catch that? Chloe said that there is no damage yet because the Cisco system is self defending. How cool is that? Now the screen shows that the Cisco security response system has prevented a security intrusion.

[D]

Self defending.

[E]

All right, have one of your people use a security auditor tool. Maybe it'll lead us to Marwan's network.

[D]

That was point from the start.

[C]

Did you catch that too? Chloe's boss just told her to use the Cisco auditing tool. And for those keeping score, in just under 45 seconds, Cisco had their product mentioned on four separate occasions.
