Editor’s observe: Incorporates main spoilers for the TV present Squid Sport.
Squid Sport, the edgy, dystopian Netflix present, has captivated audiences across the globe, leading to a fever-pitch TV second harking back to Sport of Thrones. On the floor, the present is rife with societal commentary and anti-capitalist messages about matters similar to wealth inequality. Nevertheless, viewing the present by means of the lens of a cybersecurity fanatic additionally yields a number of classes for the safety group.
On this publish, we’ll replicate on conditions within the oddly twisted world of Squid Sport and translate them into six classes for cybersecurity professionals.
Put together for Unknown ThreatsMuch just like the gamers of the Squid Sport — who should discover a technique to win at a sequence of youngsters’s video games with out understanding what sport they are going to be subjected to till they begin taking part in — safety professionals should discover methods to defend their organizations towards unexpected threats.
This has at all times been true in safety. Attackers have a bonus over safety groups as a result of, very similar to the Squid Sport host, they get to select the assault sort and vector (sport), whereas the safety groups should discover methods to defend towards numerous identified or unknown threats, and any of them can lead to a breach (or demise for the gamers).
Construct a Numerous TeamAfter the primary sport, the Squid Sport gamers shortly determined that forming an alliance would assist them survive. Not solely did it assist them dwell by means of the violence of the “midnight battle” the place roughly 15 gamers had been ruthlessly murdered by their friends, however it helped the primary characters defeat a a lot stronger workforce in tug-of-war utilizing a method Participant 001 remembered from his childhood.The lesson for cybersecurity professionals? Constructing a various workforce and expert workforce will increase the probabilities that somebody on the workforce is aware of the best technique, expertise, or data to win (cease or reply to a cyber risk).
Use the Proper ToolsTwo gamers had been in a position to smuggle in instruments after the video games had been reconvened — Sae-byeok (Participant 067) and Mi-nyeo (Participant 212), who introduced a knife and lighter, respectively. The knife allowed Sae-byeok to realize foreknowledge of the primary sport by accessing the air ducts and spying on the employees and was used within the midnight battle. The lighter helped two gamers full sport 2 by heating their needles to soften the honeycomb at a fast tempo with little threat of breaking the wafer itself.
Equally, safety groups want the best instruments to efficiently sort out the threats they face. Safety practitioners have to consistently replace their tooling so as to have the ability to discover and repair new assault techniques and to shut the gaps of their safety program. This implies periodically reflecting in your group’s capabilities, safety posture, and making an attempt to objectively determine the gaps that may be crammed given the obtainable budgets, time, and employees.
Course of MattersIn addition to having the best individuals and instruments, gamers within the Squid Sport additionally benefited massively from taking the right strategy to taking part in a sport. This was fairly actually the distinction between life and demise on many events. When Gi-hun found he might lick the honeycomb to dissolve the sugar, it gave him a large benefit over chipping away at his wafer with the needle.
Equally, when the glass producer discovered he might see the distinction between the conventional and tempered glass primarily based on the way it refracted gentle, it allowed him to advance a number of squares additional alongside the glass bridge with a lot much less threat than he would have in any other case incurred.
It is also true that safety practitioners profit from utilizing the best strategy to fixing particular issues. For instance, insider threats are greatest tackled utilizing conduct evaluation. It is also necessary for safety groups to doc their course of such that they will repeat them throughout totally different employees members and get the identical end result. As soon as one workforce member has perfected a method for one thing, like investigating malware in your atmosphere along with your tooling, they will share that data with the remainder of your workforce. The ultimate good thing about discovering and documenting your approaches is that they will then be automated with orchestration instruments.
Protection in Depth WorksParallels will be made between assembling an efficient safety posture and internet hosting a profitable Squid Sport. In each instances, you are seeking to eradicate threats (to your group, or to your prize cash) in a successive set of filters. In Squid Sport, this was achieved by subjecting the members to youngsters’s video games and eliminating the losers. Every sport eradicated a proportion of gamers till just one remained. The chart beneath reveals the effectiveness of this strategy.
Safety groups ought to take this identical strategy, however as a substitute of killing gamers, they will cease assaults utilizing complementary instruments. For instance, implementing community safety instruments (e.g., firewalls) alongside utility safety controls (e.g., a Net app firewall), endpoint safety (e.g., endpoint detection and response), e-mail safety, and identification and authentication resolution (e.g., multifactor authentication). Every successive layer of management makes it that a lot more durable for attackers to succeed. This strategy is not about constructing an “attacker-proof” safety posture, it is about slowing down hackers and making your group much less engaging as a goal. The extra layers of the onion attackers have to peel to acquire their goal, the much less possible they’re to need to proceed. Moreover, these layers decelerate attackers such that safety groups have extra time to react.
Insiders Can Additionally Be ThreatsSquid Sport has each malicious and compromised insiders. The police officer, Hwang Jun-ho, snuck into the sport to search out his brother by killing and stealing the identification of employee 29. That is analogous to a compromised insider: Jun-ho was inside the sport’s safety perimeter, used a identified identification and credentials, and was misaligned with the host’s intentions.
The organ harvesting ring is analogous to malicious insiders; they’re staff of the host group however are knowingly abusing their entry privileges to their very own ends. In each instances, these threats had been found the identical approach you need to uncover them in your IT atmosphere, by discovering irregular conduct that differs from the baseline conduct of the people concerned or their friends.
