How to Prevent Social Engineering Attacks

When it comes to cybersecurity, many think about protecting themselves against hackers who use technological flaws in a system to steal data. But cyberattacks can’t just be malware intrusions, there are other ways to infiltrate organizations and networks with the victim’s consent and without the victim’s knowledge of what is going on. This type of deception is known as social engineering, which in essence is manipulating someone until sensitive data and access permissions are granted.

A well-known example of this is when an intruder poses as the IT support of a particular company, asking users to provide information such as their usernames and passwords. The scam is accomplished when this information is shared.

It is surprising how many people do not think twice about sharing this information, especially if it looks like it is being requested by a legitimate representative.

In this context, we bring you some information relevant to the precaution against these attacks! Keep reading and learn how to protect yourself from social engineering attacks.

What Would Social Engineering Be?

The definition of social engineering embraces many types of psychological manipulations. This concept can generate positive results when it is taken to the area of behavioral promotion.

Information Security, however, tends to treat social engineering as an evil that provides benefits to the criminals, involving manipulation to obtain private information, such as personal and financial data. Thus, social engineering can also be defined as a cybercrime.

How Does Social Engineering Work?

Unfortunately, for humans, there are still some relationship patterns that are established. Social engineering works by taking advantage of these cognitive prejudice situations where criminals steal financial and personal information.

A strong example of this can be seen in the human tendency of trusting people who look nicer and more friendly, or even who hold a position of higher authority.

Social engineering techniques exploit this natural human confidence. In 2018, vacation rental phishing scams, in which hackers impersonated owners offering real vacation listings, were common enough that the US Federal Trade Commission issued a warning about them.

In many cases, the contact information and emails of the real owners were hacked, leaving little reason for victims to think they were not discussing a rental with the real owner.

Who is Most Vulnerable to Social Engineering?

Anyone can fall victim to a social engineering attack. Each one has their cognitive prejudices that, most of the time, go unnoticed during social life.

However, there are some particular groups that, in a way, are “easy” targets for these criminals, such as the elderly, who may not have knowledge of technology, generally have fewer human interactions, and may be perceived as having a lot of money and goods to discard.

What Are Common Social Engineering Techniques?

Social engineering techniques can take many forms. Below we list the commonly used techniques.

Trust Exploitation

Users are less suspicious of people they are familiar with. An attacker can become familiar with system users before the social engineering attack. The opportunist can participate in social events and other environments, which makes the attacker familiar to users.

Intimidating Circumstances 

We tend to avoid people who intimidate others around us. Using this technique, an attacker could pretend to have a heated discussion on the phone or with an accomplice to the scam, and could then ask users for information that would be used to compromise the security of their system.

Users are more likely to give the correct answers just to avoid a confrontation with the criminal. This technique can also be used to avoid being checked at a security checkpoint.

Phishing

This technique uses tricks and cheats to obtain users’ private data. The social engineer might try to impersonate a genuine website, such as Google, and then ask the unsuspecting user to confirm their account name and password.

This technique can also be used to obtain credit card information or any other valuable personal data.

Exploring Human Curiosity

Using this technique, the social engineer can deliberately leave a virus-infected USB stick in an area where users can easily pick it up. The user will likely connect the USB stick to the computer.

Thus, the USB stick might run the virus automatically or the user might be tempted to open a file with a name, such as Employee Review Report 2013.docx, which might actually be an infected file.

Exploring Human Greed

Using this technique, the social engineer can entice the user with the promise of earning big money online by filling out a form and confirming their details using credit card details, etc.

How to Protect Yourself from a Social Engineering Attack?

Social engineering attacks are stealthy. This makes it critical for everyone to be aware of the threat. Some best practices you can follow to ensure you are protecting yourself from social engineering attacks include:

  • Never responding to a request for financial information or passwords. Legitimate organizations will not send a message asking for personal information.
  • Adjusting your spam filters. Every email program has spam filters, make sure yours is set to block potential threats.
  • Protect your computing devices and accessories. That means protecting your digital space with antivirus software, firewalls, and email filters. It also means protecting USB sticks, external hard drives, and other pieces of equipment that could be compromised.

Finally, managers must develop plans to raise awareness among the staff. There are many essential precautions available on the internet, and for corporate environments, the in-house team needs to be aware of how to protect against digital threats.

Making sure employees are aligned for this purpose is an essential step in the process of preventing social engineering attacks and other cyberattacks.

Why GREYCORTEX Mendel Is the Essential Member of Your Network Security Product Family

There are several basic tools for securing network infrastructure that should not be missing from any organization. Let’s take a look at the role of GREYCORTEX Mendel in all those products protecting the data and network in your company.

Antivirus software, firewalls and intrusion prevention systems (IPS) should be an integral part of any organization’s cybersecurity solution. Nowadays, however, they are often not enough. That’s where Mendel steps in.

GREYCORTEX Mendel stands on several levels:

  • It is a unique tool that sees, visualizes and analyzes everything in your network – devices, access and all communications.
  • It is a great extension to the functionality of standard cybersecurity tools: antivirus, firewalls and network performance monitoring. They are crucial, but there are some threats that even they cannot detect. The reason is simple: attackers are often ready for these standard systems.

Mendel Sees and Visualizes in the Context of Time and Events

Imagine a tool that sees all the devices in your network, how they are communicating together, what protocols they are using and where your data is going. With Mendel, you can see all of that. You can also view the details of a specific device, its communication and where it is connected to at the moment, and also yesterday or a year ago.

With this unique analysis, you can uncover a sophisticated attack on your infrastructure before it really happens. That’s because you can relate current events to events that happened before, even in the more distant past.

Let’s take a look at an example of an attack that may go unnoticed by a standard detection mechanism: Advanced malware is not detected on the end device, but that device shows behavior that could endanger the network – for example, trying to access somewhere it has not accessed before. It could be spyware or an APT in your internal domains that is gradually spreading across your network through a domain, while the infected machines start accessing unusual devices and data sources and performing lateral movement. Mendel can identify and notify you of such unusual behavior.

More Reliable End-Point Security

Because end-points are an easy target, often provide valuable data and are an entry point for gaining deeper access to your network, they are the frequent initial targets of cyber-attacks.

Commonly known end-point attacks include:

  • network mapping
  • data exfiltration (sending data in non-standard or encrypted channels, communication with control devices)
  • Dictionary attacks, password data breaches
  • Data mining (reading important information, mining data from a database, mining users from information systems or from a domain controller)

Mendel flags such attacks as dangerous behavior and recognizes the threat that might not have been recognized by endpoint security or that is well hidden by the attacker. Even if antivirus software is deployed, Mendel monitors the communication of your devices and reveals any anomalies in it. All of that using a broad database specializing in network cyber threats that include not only known threats but also signatures of unusual behavior.

A Smarter Firewall

We can understand a few things that fall under the term firewall: standard firewalls and smart solutions known as an IPS.

Traditional firewalls stand first in the line of defense and secure broad traffic filtering. They adjust network transitions and the availability of network services and are mostly used on the external perimeter – in some cases within the internal network. They are often open or insufficiently configured.

In such cases, Mendel plays the role of an auditing tool – controlling the function of the firewall itself and checking its configuration. You can use this feature for verifying and controlling the communication matrix in your internal network and critical systems. It helps you understand who is connecting where, who is using what and who is behaving differently than they should.

Smart solutions such as IPS see more deeply into your network, can detect known threats and block them. Also here, Mendel provides you a double-check by monitoring the operation of web proxies and email gateways. This means no potential threat can pass. Even in this case, Mendel’s advantage is its extensive database of threats, consisting of multiple sources and signatures that verify not only known attacks but also security policies and potentially dangerous access to data sources, such as administrative sharing. This approach is much more effective for the detection of vulnerabilities than just a database of known threats from one vendor.

This way, Mendel shows much more – not only what needs to be blocked but also unwanted or insecure applications and access to risky services. You’ll get a much better overview of what is going on and what is going through your network and how.

The Danger of Unknown Threats

In all mentioned cases, Mendel not only deals better with detecting known threats, its strength lies in also detecting unknown threats. How? Mendel recognizes different types of actions using behavioral analysis.

Right after anomalous behavior or an unknown threat is detected, the system notifies you, for example, by email. It’s then your choice. You can either take the necessary steps or you can connect Mendel to the firewall API and it will block the unwanted communication automatically for you.

A Huge Help for Monitoring Network Performance

At the next level, there are tools for internal system monitoring. In this case, Mendel shows a clear overview of the network – how it is loaded and used, who is accessing it, what services are operating and what the performance of applications and transmission lines is.

Imagine seeing just how loaded your information system, domain controller, Wi-Fi network or data center are!

GREYCORTEX Mendel helps you increase the reliability of your network. Even industrial control systems can get the right amount of control, so any attack or even a major network failure has no catastrophic consequences.

Antivirus software shows you current threats. A firewall displays the current settings and whether it is leaking something or not. But nothing will clearly show you events in your network an hour, a week or a year ago. In a nutshell, Mendel sees, visualizes and (thanks to data storage of up to the last several years) also analyzes current as well as past events.

Pandora FMS and Nagios back in the ring. The final comparison

The battle begins again: Pandora FMS Vs Nagios. ¡FIGHT!

NagiosXI is the proprietary heir of one of the best-known tools in IT to monitor systems without a license, that is, as a free product. As a free product, Nagios (without XI) is a product that is almost 20 years old and suffers from many shortcomings, but for many years it has been the standard among “free” products and it fulfilled its role in those cases where the budget was quite short or the features needed were just a few. In recent years, its role as a free tool has been replaced by the more modern Zabbix.

Product features

Nagios XI is not a product as such, but rather it combines several pre-existing independent components. The best example is, for example, Nagios XI WEB management interface, with several elements, each one with its own credential system. Other system components installed on the Nagios XI appliance include:

  • Nagios XI UI: “Overlying” interface on the “basic” Nagios interface.
  • Nagios Core: Traditional interface.
  • NSCA: Agent for passive and plugin tests (not maintained since 2011).
  • NSPA: Agent for passive and plugin tests, with remote management.
  • NRPE: Agent for running Nagios plugins.
  • NRDP: Agent, theoretically a replacement for NSCA, whose development has not been updated since 2012.
  • Nagios Plugins: Monitoring scripts. There have been several community “forks”.
  • NagiosFusion: System similar to Pandora FMS Metaconsole.
  • Netflow Analyzer: Specific component to work with Netflow/SFlow flows.
  • Nagios Log Server: Log storage and monitoring system.

Each component with WEB interface has its own “look & feel”, its own user management system and, of course, its own configuration and integration with other elements. And these are elements designed by the company itself, Nagios Enterprise.

Third-party “OpenSource” components

  • PNP: Plugin to monitor performance using RRD binary databases.
  • Nagvis (maps): User-defined maps.
  • NDOUtils: Information export from nagios to SQL.
  • NSClient ++: Alternative agent that supports Nagios/Icinga.
  • NagiosQL (modified): Administration interface with data storage in MySQL.

None of these elements, which make up the “Nagios XI” solution, are even by Nagios itself, so the compatibility and coherence between them is relative. In many cases, no one can guarantee the quality or maintainability of those pieces of software.

Points against Nagios

Monitoring current technologies

New check creation is based on wizards or plugins. In both cases, you have to be an expert to modify any of them (you have to program at command level, know the specific template definition language and manually debug), which makes it difficult to broaden the variety of checkups or customize one of them easily from the interface itself. In Pandora FMS, any extension can be carried out using the WEB interface, without getting down to the console level, in addition to offering a bigger plugin collection for business software that does not require any kind of coding.

When applying settings, you need to “compile” them so that if something goes wrong, changes cannot be applied until they are corrected. This would be insane in an environment with many hosts. Deleting an agent without first deleting the service it contains prevents you from making the change, but it does not solve it, for example. In Pandora FMS, the entire operation is in real time, or in the case of applying major changes, managed in the background by the system, without interruptions or the need to interact at a low level with the system.

Management automation

In general, monitoring is so manual that it would take a long time to monitor 100 agents, unless low-level scripts are created to automate the whole process, so there is no standard nor tools that allow automation, or good practices, it depends exclusively on the ability of the “nagios expert” to automate these tasks efficiently, which is a completely manual process.

Reports

Although Nagios has “custom” reports, this customization is limited to parameterizing the already available reports, which are only of 20 types. Each report shows a type of information available with a pre-set presentation, for example the SLA:

nagios1

Filters can be added and saved as favorites, but it is not a report that can be much more customized. To sum up, reports are intended for the technician’s use, never to be used for an internal or external client. Reports do not allow to combine different types of elements or to show generic graphs of specific metrics.

Usability in large environments

Console load for very few agents is extremely high. The usability with a high number of systems is very poor. Although it can be made to monitor many systems, it clearly has not been designed for it. Pandora FMS is currently being used to operate and manage systems with more than 100,000 nodes.

Windows Agents

Nagios “Advanced” Agents for Windows (NSCA) are from 2011 and there have been no updates since then. There are several “Forks” (iCinga, ISCA-NG), but not for Windows. Despite the fact that Nagios has up to four types of agents (NRPE, NSCA), their performance and power is far from being comparable to that of Pandora FMS, especially in Windows environments.

Performance monitoring

Until very recently, Nagios used third-party software to manage performance data and graphics. It has now been integrated, but it remains a tailored third-party component, and not part of its initial architecture. Pandora FMS is a native capacity tool, it can be used to elaborate dashboards, since it works with data and an SQL engine from its first version.

Lack of event management

Nagios does not perform event-based management, it cannot automatically validate events from monitors that have been retrieved, it cannot group them, and it cannot specify event-based alerts. To tell you the truth, there is no “event” concept in Nagios as in other tools (OpenView, Tivoli, Patrol, SCOM, Spectrum, etc). Pandora FMS has evolved based on requirements of former users of these tools, so the level of compliance with industry standards is very high.
For Nagios, the events consist of a text log for a simple visual review, as seen in the following screenshot:

nagios2.

Nagios cannot do a root cause analysis,

Since there is no event correlation. PandoraFMS does have it, and it also has multiple tools (L2 Maps, Services, Alert Escalation, Cascade Protection) that help the user in this regard.

Nagios cannot do BPM (service monitoring)

With Nagios you cannot set a hierarchy based on weights of different elements from different systems. Pandora FMS has a specific component (Service Maps) for this specific point.

Network level deficiencies.

Nagios cannot display a physical network, since it is not capable of detecting or displaying link-level topologies. This limits switch and router monitoring. Furthermore, its network maps are not interactive nor can they be edited or customized unlike Pandora FMS Enterprise.

Its SNMP trap monitoring is not integrated with monitoring and therefore no added graphs, reports or alerts can be displayed. The same applies for its Netflow monitoring interface, which is conceived as an auxiliary tool.

Dashboard and custom visual displays

The closest thing to Pandora FMS visual consoles on Nagios are the third-party NAGVIS plugin that has barely evolved in the last 15 years. Nagvis is an external plugin, which is not even fully integrated with Nagios XI. Even going so far as to have a different look & feel:

nagios3

Although Nagios also has a Dashboard with a concept similar to that of Pandora FMS, it does not have basic elements, such as showing graphs of each monitored element, or numerical data of the collected values. It happens in a similar way with reports, which have “predefined” elements that provide little or no flexibility when it comes to building your own dashboards.

Permission management and Multi-tenancy

NagiosXI is not intended to work in a complex organization, where different administrators and users with access to different groups of machines can coexist. Its access segregation is very basic:

nagios4

The scenario where you may have several dozen, with different ACL permissions by user groups is not even contemplated. Although it has an audit log, it is not useful to know what the administrator or users do with the tool, it is more like a server diagnostic tool.

Conclusions

Nagios is a software tool that can be useful in environments where there is already a person with advanced knowledge of Nagios who takes care of everything and adapts it manually according to the needs of the environment. The company does not have a “Nagios”, it has a “person who knows about Nagios”, so the cost of the total solution is really the cost of that person, including a possible replacement. In this case you don’t pay for license nor maintenance, but the hidden costs are of other nature. Tool customization and evolution depends entirely on that person. It is not a standard solution, it is a completely “ad-hoc” solution.

100% of our clients, prospects or consulted companies that use Nagios, actually use the “free” version of Nagios, which has less features than those included in this comparison. There are many Nagios forks, the most popular are Icinga or Centreon. There are commercial alternatives with a higher quality than that of Nagios XI, the best representative would be OP5.

Nagios XI is a tool whose main strength is its license price, which in most cases is free, and which even in the case of paying for the “Enterprise” version is more competitive than Solarwinds or Whatsup Gold just to name a few.

Pandora FMS is a tool that competes – and has already replaced in several cases – tools from IBM, HP, CA and BMC such as Tivoli, OpenView, Spectrum and Patrol. The scope, resources and scope of the projects are clearly different.
