Using an unordered list, summarize the following article with between 4 and 8 key points. <\/p>\n

From the castle builders of yore to the cybersecurity experts of today, one lesson never gets old: there\u2019s no such thing as the perfect one-layer defense. You can install the deepest moat, or the thickest wall, or the most robust endpoint security protections, but if that\u2019s your only protection, it will not hold. Throughout history, those tasked with security have either accepted this fact, or learned it again the hard way.
\nWhile there\u2019s no such thing as a perfect single layer defense (and arguably no \u201cperfect\u201d defense in general), defenders are much more successful implementing strategies that stack up multiple layers of defenses. Wise medieval architects, to stick with my theme, made the moat just the first of many obstacles designed to stop attackers, placing a deliberate series of external and internal walls and gates in their path. Cybersecurity teams should follow that example by securing systems and data with measures that bar attackers at each step they might take toward achieving a breach. The more layers to get through, the more likely they are to move on to someone else\u2019s proverbial castle.\u00a0
\nAllow me to share a recent cautionary tale from a colleague in the cybersecurity industry, one that highlights the danger of relying too heavily on perimeter defenses. A business in the oil and gas sector believed that if they could stop attackers at the edge, they could prevent any security issues entirely. That logic makes sense on paper, but it breaks down in practice. You have to assume that attackers will always find the cracks.
\nIn this case, the business had just about every device and attack surface as locked down as you can get\u2026with the exception of a single postal meter. That one overlooked endpoint wasn\u2019t missed by attackers, who snuck in through that gap and then collected all the data they wanted with extraordinary ease. In the aftermath of that disaster, my colleague (part of an MSP) was brought in to stand up additional layered security protections that could have prevented the negative incident, and saved the business a heck of a lot of trouble.
\nInterior defense: layered encryption and access controls\u00a0
\nData encryption is crucial to ensuring that even when attackers do manage to reach sensitive data, they can\u2019t grasp it. Introducing layered encryption multiplies that protection by rendering data unreadable at both the network and the device level.\u00a0
\nWith single layer system-level encryption (Bitlocker, for example), network-borne attacks that manage to evade a business\u2019s network firewall and remotely log into a PC will see all data in its decrypted form. However, including additional device-level encryption will make it so that a network breach is not synonymous with a data breach.
\nAt the same time, segmenting data access and practicing the principle of least-privilege access is crucial to a layered security strategy. If an attacker that compromises a single set of login credentials is allowed to have the run of an organization\u2019s data and systems, that business is in for a bad day. In contrast, if each employee\u2019s access is limited to only the data they require, the scope of any breach is greatly compartmentalized, and risks are kept to a minimum.
\nRansomware without leverage
\nRansomware attackers have two nefarious methods for profiting off from the data they manage to compromise. The traditional method (that gave ransomware its name) is to encrypt an organization\u2019s data and disallow access until that business pays their ransom. To thwart this method, organizations need another layer of data protection in the form of secure data backups, meaning that a business can simply restore their systems and ignore the ransom request.
\nHowever, attackers also have a backup plan, Ransomware 2.0: their second method is to hold data hostage by threatening to sell it to buyers on the dark web, or simply release it if a ransom isn\u2019t paid. Fortunately, layered encryption defeats this method. Ransomware attackers might think of themselves as masters of encryption, but they can\u2019t read data to expose it if an organization has its own device-level encryption in place.
\nDefense that holds
\nCyberattacks come in myriad flavors, and no one layer of security protections can hope to defeat them all. By adopting a layered security strategy that places protections throughout an organization\u2019s proverbial castle (while limiting attack surfaces and risks), it becomes possible to build a defense capable of holding strong against nearly any challenge.
