In Wireless Sensor Network (WSN), where nodes besides having its inbuilt capability of sensing, processing and communicating data, also possess some risks. These risks expose them to attacks and bring in many security challenges. Therefore, it is imperative to have a secure system where there is perfect confidentiality and correctness to the data being sent from one node to another. Cooperation among the nodes is needed so that they could confidently rely on other nodes and send the data faithfully. However, owing to certain hardware and software faults, nodes can behave fraudulently and send fraudulent information. Nevertheless, since the network is openly accessible, anybody can access the deployment area which breaches the security of WSN. Therefore, it is required to have correct and accurate secure model for WSN to protect the information and resources from attacks and misbehavior. Many researchers are engaged in developing innovative design paradigms to address such nodes by developing key management protocols , secure routing mechanisms and trust management systems. Key management protocols and secure routing cannot itself provide security to WSNs for various attacks. Trust management system can improve the security of WSN. The case study begins by explaining the security issues and challenges in WSN. It discusses the goals, threat models and attacks followed by the security measures that can be implemented in detection of attacks. Here, various types of trust and reputation models are also reviewed. The intent of this case study is to investigate the security related issues and challenges in wireless sensor networks and methodologies used to overcome them. Furthermore, the present case study provides details on how bio-inspired approaches in WSN prove a benefactor in many ways.

7 Data Breach Examples Involving Human Error: Did Encryption Play a Role?

Despite an overall increase in security investment over the past decade, organizations are still plagued by data breaches. What’s more, we’re learning that many of the attacks that result in breaches misuse encryption in some way. (By comparison, just four percent of data breaches tracked by Gemalto’s Breach Level Index were “secure breaches” in that the use of encryption rendered stolen data useless). Sadly, it’s often human error that allows attackers access to encrypted channels and sensitive information. Sure, an attacker can leverage “gifts” such as zero-day vulnerabilities to break into a system, but in most cases, their success involves provoking or capitalizing on human error.

Human error has a well-documented history of causing data breaches. The 2022  Global Risks Report  released by the World Economic Forum, found that 95% of cybersecurity threats were in some way caused by human error. Meanwhile, the  2022 Data Breach Investigations Report  (DBIR) found that 82% of breaches involved the human element, including social attacks, errors and misuse. 

I think it’s interesting to look at case studies on how human error has contributed to a variety of data breaches, some more notorious than others. I’ll share the publicly known causes and impacts of these breaches. But I’d also like to highlight how the misuse of encryption often compounds the effects of human error in each type of breach.

Data breach examples.

Here is a brief review of seven well-known data breaches caused by human error.

1. Equifax data breach—Expired certificates delayed breach detection

In the spring of 2017, the U.S. Department of Homeland Security's Computer Emergency Readiness Team (CERT) sent consumer credit reporting agency Equifax a notice about a vulnerability affecting certain versions of Apache Struts. According to former CEO Richard Smith, Equifax sent out a mass internal email about the flaw. The company’s IT security team should have used this email to fix the vulnerability, according to Smith’s testimony before the House Energy and Commerce Committee. But that didn’t happen. An automatic scan several days later also failed to identify the vulnerable version of Apache Struts. Plus, the device inspecting encrypted traffic was misconfigured because of a digital certificate that had expired ten months previously. Together, these oversights enabled a digital attacker to crack into Equifax’s system in mid-May and maintain their access until the end of July.

How encryption may become a factor in scenarios like this:  Once attackers have access to a network, they can install rogue or stolen certificates that allow them to hide exfiltration in encrypted traffic. Unless HTTPS inspection solutions are available and have full access to all keys and certificates, rogue certificates will remain undetected.

Impact:  The bad actor is thought to have exposed the personal information of 145 million people in the United States and more than 10 million UK citizens. In September 2018, the Information Commissioner’s Office  issued Equifax a fine of £500,000, the maximum penalty amount allowed under the Data Protection Act 1998, for failing to protect the personal information of up to 15 million UK citizens during the data breach.

2. Ericsson data breach—Mobile services go dark when the certificate expires

At the beginning of December 2018, a digital certificate used by Swedish multinational networking and telecommunications company Ericsson for its SGSN–MME (Serving GPRS Support Node—Mobility Management Entity) software expired. This incident caused outages for customers of various UK mobile carriers including O2, GiffGaff, and Lyca Mobile. As a result, a total of 32 million people in the United Kingdom alone lost access to 4G and SMS on 6 December. Beyond the United Kingdom, the outage reached 11 countries including Japan.

How encryption may become a factor in scenarios like this: Expired certificates do not only cause high-impact downtime; they can also leave critical systems without protection. If a security system experiences a certificate outage , cybercriminals can take advantage of the temporary lack of availability to bypass the safeguards.

Impact:  Ericsson restored the most affected customer services over the course of 6 December. The company also noted in a  blog post  that “The faulty software [for two versions of SGSN–MME] that has caused these issues is being decommissioned.”

3. LinkedIn data breach—Millions miss connections when the certificate expires

On 30 November, a certificate used by business social networking giant LinkedIn for its country subdomains expired. As reported by The Register , the incident did not affect www.linkedin.com, as LinkedIn uses a separate certificate for that particular domain. But the event, which involved a certificate issued by DigiCert SHA2 Secure Server CA, did invalidate us.linkedin.com along with the social media giant’s other subdomains. As a result, millions of users were unable to log into LinkedIn for several hours.

How encryption may become a factor in scenarios like this:  Whenever certificates expire, it may indicate that overall protection for machine identities is not up to par. Uncontrolled certificates are a prime target for cybercriminals who can use them to impersonate the company or gain illicit access.

Impact:  Later in the afternoon on 30 November, LinkedIn deployed a new certificate that helped bring its subdomains back online, thereby restoring all users’ access to the site.

4. Strathmore College data breach—Student records not adequately protected

In August 2018, it appears that an employee at Strathmore secondary college accidentally published more than 300 students’ records on the school’s intranet. These records included students' medical and mental health conditions such as Asperger’s, autism and ADHD. According to The Guardian , they also listed the exposed students’ medications along with any learning and behavioral difficulties. Overall, the records remained on Strathmore’s intranet for about a day. During that time, students and parents could have viewed and/or downloaded the information.

How encryption may become a factor in scenarios like this:  Encrypting access to student records makes it difficult for anyone who doesn’t have the proper credentials to access them. Any information left unprotected by encryption can be accessed by any cybercriminals who penetrate your perimeter.

Impact:  Strathmore’s principal said he had arranged professional development training for his staff to ensure they’re following best security practices. Meanwhile, Australia’s Department of Education announced that it would investigate what had caused the breach.

5. Veeam data breach—Customer records compromised by unprotected database

Near the end of August 2018, the Shodan search engine indexed an Amazon-hosted IP. Bob Diachenko, director of cyber risk research at Hacken.io, came across the IP on 5 September and quickly determined that the IP resolved to a database left unprotected by the lack of a password. The exposed database contained 200 gigabytes worth of data belonging to Veeam, a backup and data recovery company. Among that data were customer records including names, email addresses and some IP addresses.

How encryption may become a factor in scenarios like this:  Usernames and passwords are a relatively weak way of securing private access. Plus, if an organization does not maintain complete control of the private keys that govern access for internal systems, attackers have a better chance of gaining access.

Impact:  Within three hours of learning about the exposure, Veeam took the server offline. The company also reassured  TechCrunch  that it would “conduct a deeper investigation and… take appropriate actions based on our findings.”

6. Marine Corps data breach—Unencrypted email misfires

At the beginning of 2018, the Defense Travel System (DTS) of the United States Department of Defense (DOD) sent out an unencrypted email with an attachment to the wrong distribution list. The email, which the DTS sent within the usmc.mil official unclassified Marine domain but also to some civilian accounts, exposed the personal information of approximately 21,500 Marines, sailors and civilians. Per Marine Corp Times , the data included victims’ bank account numbers, truncated Social Security Numbers and emergency contact information.

How encryption may become a factor in scenarios like this:  If organizations are not using proper encryption, cybercriminals can insert themselves between two email servers to intercept and read the email. Sending private personal identity information over unencrypted channels essentially becomes an open invitation to cybercriminals.

Impact:  Upon learning of the breach, the Marines implemented email recall procedures to limit the number of email accounts that would receive the email. They also expressed their intention to implement additional security measures going forward.

7. Pennsylvania Department of Education data breach—Misassigned permissions

In February 2018, an employee in Pennsylvania’s Office of Administration committed an error that subsequently affected the state’s Teacher Information Management System (TIMS). As reported by PennLive , the incident temporarily enabled individuals who logged into TIMS to access personal information belonging to other users including teachers, school districts and Department of Education staff. In all, the security event is believed to have affected as many as 360,000 current and retired teachers.

How encryption may become a factor in scenarios like this: I f you do not know who’s accessing your organization’s information, then you’ll never know if it’s being accessed by cybercriminals. Encrypting access to vital information and carefully managing the identities of the machines that house it will help you control access.

Impact:  Pennsylvania’s Department of Education subsequently sent out notice letters informing victims that the incident might have exposed their personal information including their Social Security Numbers. It also offered a free one-year subscription for credit monitoring and identity protection services to affected individuals.

How machine identities are misused in a data breach

Human error can impact the success of even the strongest security strategies. As the above attacks illustrate, this can compromise the security of machine identities in numerous ways. Here are just a few:

• SSH keys grant privileged access to many internal systems. Often, these keys do not have expiration dates. And they are difficult to monitor. So, if SSH keys are revealed or compromised, attackers can use them to pivot freely within the network.
• Many phishing attacks leverage wildcard or rogue certificates to create fake sites that appear to be authentic. Such increased sophistication is often required to target higher-level executives.
• Using public-key encryption and authentication in the two-step verification makes it harder to gain malicious access. Easy access to SSH keys stored on computers or servers makes it easier for attackers to pivot laterally within the organization.
• An organization’s encryption is only as good as that of its entire vendor community. If organizations don’t control the keys and certificates that authenticate partner interactions, then they lose control of the encrypted tunnels that carry confidential information between companies.
• If organizations are not monitoring the use of all the keys and certificates that are used in encryption, then attackers can use rogue or stolen keys to create illegitimate encrypted tunnels. Organizations will not be able to detect these malicious tunnels because they appear to be the same as other legitimate tunnels into and out of the organization.

How to avoid data breaches

The best way to avoid a data breach to make sure your organization is using the most effective, up-to-date security tools and technologies. But even the best cybersecurity strategy is not complete unless it is accompanied by security awareness training for all who access and interact with sensitive corporate data. 

Because data breaches take many different forms and can happen in a multitude of ways, you need to be ever vigilant and employ a variety of strategies to protect your organization. These should include regular patching and updating of software, encrypting sensitive data, upgrading obsolete machines and enforcing strong credentials and multi-factor authentication.

In particular, a zero-trust architecture will give control and visibility over your users and machines using strategies such as least privileged access, policy enforcement, and strong encryption. Protecting your machine identities as part of your zero trust architecture will take you a long way toward breach prevention. Here are some machine identity management best practices that you should consider: 

• Locate all your machine identities.  Having a complete list of your machine identities and knowing where they’re all installed, who owns them, and how they’re used will give you the visibility you need to ensure that they are not being misused in an attack.
• Set up and enforce security policies.  To keep your machine identities safe, you need security policies that help you control every aspect of machine identities — issuance, use, ownership, management, security, and decommissioning. 
• Continuously gather machine identity intelligence.  Because the number of machines on your network is constantly changing, you need to maintain intelligence their identities, including the conditions of their use and their environment. 
• Automate the machine identity life cycle.  Automating he management of certificate requests, issuance, installation, renewals, and replacements helps you avoid error-prone manual actions that may leave your machine identities vulnerable to outage or breach. 
• Monitor for anomalous use.  After you’ve established a baseline of normal machine identity usage, you can start monitoring and flagging anomalous behavior, which can indicate a machine identity compromise.
• Set up notifications and alerts.  Finding and evaluating potential machine identity issues before they exposures is critical. This will help you take immediate action before attackers can take advantage of weak or unprotected machine identities.
• Remediate machine identities that don’t conform to policy.  When you discover machine identities that are noncompliant, you must quickly respond to any security incident that requires bulk remediation.

Training your users about the importance of machine identities will help reduce user errors. And advances in AI and RPA will also play a factor in the future. But for now, your best bet in preventing encryption from being misused in an attack on your organization is an automated machine identity management solution that allows you to maintain full visibility and control of your machine identities. Automation will help you reduce the inherent risks of human error as well as maintain greater control over how you enforce security policies for all encrypted communications.

More on the Trump Jan. 6 case

The latest: The Supreme Court will review Donald Trump’s unprecedented claim that he is shielded from prosecution for actions taken while in office. Supreme Court arguments are set for the week of April 22. Here’s what happens next .

The charges: Former president Donald Trump pleaded not guilty to charges that he plotted to overturn the 2020 election in the run-up to the Jan. 6, 2021, attack on the U.S. Capitol. Here’s a breakdown of the charges against Trump and what they mean, and things that stand out from the Trump indictment . Read the full text of the 45-page indictment .

The trial: The March 4 trial date has been taken off the calendar and jury selection has been postponed indefinitely while Trump’s claim of presidential immunity from criminal prosecution remains on appeal .

The case: The special counsel’s office has been investigating whether Trump or those close to him violated the law by interfering with the lawful transfer of power after the 2020 presidential election or with Congress’s confirmation of the results on Jan. 6, 2021. It is one of several ongoing investigations involving Trump .

Can Trump still run for president? While it has never been attempted by a candidate from a major party before, Trump is allowed to run for president while under indictment in four separate cases — or even if he is convicted of a crime.
