Cyber Security is the practice of defending computers, servers, mobile devices, electronic systems, networks and data from malicious attacks. It is also known as Information Technology Security and Electronic Information Security . The term applies in a wide variety of contexts, from business to mobile computing and can be divided into a few common categories.
We can divide cyber security into several areas of interest which I list briefly below. In almost every situation listed, SOD has a dedicated service.
Cyber Security areas of interest
network security is the practice of protecting a computer network from intruders, whether it is targeted attacks or generic malware .
application security focuses on keeping software and devices free from threats. A hacked application may be providing access to data that it was designed to protect. Robust security begins in the design phase , well before a program or device is deployed. This is why analyzing the code of an app is essential before it is released.
operational security includes processes and decisions in the management and protection of resources and data. The permissions that users have when accessing a network and the procedures that determine how and where data can be stored or shared all fall within this scope.
Disaster recovery and business continuity define how an organization is able to respond to a cyber security incident or any other event that causes data loss . Disaster recovery policies dictate how the organization restores its operations and information to return to the same operational capacity as before the event. business continuity is the plan the organization resorts to as it tries to operate without certain resources.
The human part of cyber security
End User Education addresses the most unpredictable factor in cybersecurity: people . Anyone can accidentally introduce a virus into an otherwise secure system by not following security best practices. For example, teaching users to delete suspicious email attachments and not insert unidentified USB drives is vital to the security of any organization .
In this area, particular importance should be given to scams, phishing and in general social engineering, which relies on the element usually more weak computer system: the operator.
The scope of cyber threats
The global cyber threat continues to evolve at a rapid pace, with a increasing number of data breaches every year . A report from RiskBased Security revealed that 7.9 billion documents were exposed to data breaches in the first nine months of 2019. This figure is more than double (112%) of the number of documents exposed in the same period the previous year.
I medical services , retailers and government agencies have experienced the most breaches , with malicious criminals responsible for most accidents. Some of these industries are more attractive to cybercriminals because they collect financial and medical data, but all companies using networks can be targeted for their customers’ data, corporate espionage, or to attack customers .
What governments do
With the scale of the cyber threat set to continue to grow, the International Data Corporation predicts global spending on cyber security solutions will reach a record $ 133.7 billion by 2022 . Governments around the world have responded to the growing cyber threat with guidance to help organizations implement effective cybersecurity practices.
In the United States, the National Institute of Standards and Technology (NIST) has created a cyber security framework , to combat the proliferation of malware code and aid early detection. The framework recommends continuous, real-time monitoring of all electronic assets .
The importance of system monitoring is resumed in the “ 10 steps to cybersecurity “, a guide provided by the UK government’s National Cyber Security Center . In Australia, the Australian Cyber Security Center (ACSC) regularly publishes guidance on how organizations can counter the latest cybersecurity threats.
In Italy we have the national framework for cyber security which provides tutorials, guides and European standards on cyber security .
MSSP and cyber security services
A Managed Security Service Provider (MSSP) provides monitoring and management in outsourcing for security devices and systems. In practice it takes care of all cyber security measures for the company requesting the services.
SOD is an MSSP and the services offered include protection and monitoring of various sectors of the corporate IT department.
Our verification services include vulnerability and penetration testing , as well as the analysis of safety procedures . With the SOC as a Service service we provide the potential of a Security Operation Center , relieving the company of installation and management costs. The SOC adopts latest generation technologies such as SIEM Next Gen and UEBA , which introduce analysis by an AI for motoring logs and users .
SOD uses security operations centers to provide 24/7 services designed to reduce the number of operational personnel that a company must manage, while still guaranteeing levels of cyber security excellent.
But defense fronts don’t stop at software and machines, must also include the most unpredictable element: the end user . That’s why our offer for companies also includes people-oriented services, as we will see shortly.
End user protection
End user protection is a crucial aspect of cyber security . After all, it is often the end user who accidentally loads a malware or other form of malware on their device .
As suggested earlier, the security protocols set up by SOD analyze software in real time. Through behavioral analysis systems we can monitor both the behavior of a software and the user . In the case of an attack based on lateral movement , for example, abnormal accesses and requests by a user can be indicators of an attack in progress.
But we don’t stop there, we can test the company against techniques of social engineering , phishing and physical tampering. Thanks to the ethical hacking services and consequent report, we are able to identify the company’s weak points and suggest effective strategies to mitigate the risks. In the case of phishing, we also organize ad hoc training based on the weaknesses highlighted in the report.
Through the physical security service, in addition to the IT vulnerability testing services, we put ourselves in the play the bad guys and try to carry out physical attacks . For example, we try to enter corporate buildings that should be protected, we try to reach network infrastructures and install potentially harmful hardware, etc.
Thanks to a team of ethical hackers and trained and trained operators, we test every aspect of cyber security before a risk becomes a problem .
If you want more information about our services or have any questions, don’t hesitate to contact us.
A legitimate question that often arises is whether the Penetration Test is necessary for compliance with the ISO 27001 standard. To fully understand the answer, it is necessary to clarify what is meant by these terms and to understand the relationship between all the components of the certification.
ISO 27001 standard
A technical standard, also incorrectly called a standard, is a document that describes the specifications that a certain object / body / entity must comply with in order to be certified. In general, a standard describes the requirements of materials, products, services, activities, processes, terminology, methodologies and other aspects concerning the subject of the standard. In very simple words, norms are rules that regulate almost everything by offering constructive and methodological standards.
The ISO 27001 standard (ISO / IEC 27001: 2013) is the international standard that describes the best practices for an ISMS, Information Security Management System. Although following the standard is not mandatory, it is necessary to obtain a certification to guarantee logical, physical and organizational security.
Obtaining an ISO 27001 certification demonstrates that your company is following information security best practices and provides independent and qualified control. Safety is guaranteed to be in line with the international standard and company objectives.
Of great importance for the ISO 27001 standard is Annex A “Control objective and controls”, which contains the 133 controls that the company concerned must comply with.
Vulnerability Assessment and Penetration Test
When performing a Vulnerability Assessment on the network and computer systems, the aim is to identify all technical vulnerabilities present in operating systems and software. Some examples of vulnerabilities can be SQL Injection, XSS, CSRF, weak passwords, etc. The vulnerability detection indicates that there is a recognized security risk due to a problem of some kind. It does not say whether or not it is possible to exploit the vulnerability. To find out, it is necessary to carry out a Penetration Test (or pentest).
To explain the above, imagine that you have a web application that is vulnerable to SQL Injection which could allow an attacker to perform operations on the database. A VA identifies this vulnerability, ie it may be possible to access the database. Following the vulnerability assessment, if a pentest is performed and the vulnerability can be exploited, the risk would be demonstrated.
To comply with control A.12.6.1 of Annex A of the ISO 27001 standard, it is necessary to prevent the exploitation of technical vulnerabilities. However, the decision on how to proceed is up to you. Is it therefore necessary to perform a Pentest? Not necessarily.
After the vulnerability analysis, we could fix and fix the weaknesses and eliminate the risk before performing a pentest. Therefore, for the purposes of compliance with the ISO 27001 standard, the required result can be obtained simply by performing the vulnerability assessment and solving the potential problems that have arisen.
Having said that, we strongly recommend that you carry out a complete Penetration Test to be really sure of compliance with the standard. It can help you prioritize problems and tell you how vulnerable your systems are.

Security: pentest and verification of vulnerabilities
The security of computer networks is of vital importance for a company. With technologies increasingly relying on remote services, it is good to ensure that security is guaranteed. To do this, two tools are used: Vulnerability Assessment and Penetration Test. But what is the difference between them? The answer to this question is not as obvious as one might think.
The short answer is: a Pentest (PT) may be a form of vulnerability assessment (VA), but a vulnerability assessment is definitely not a Pentest. Let’s try to better understand how they work and their purposes.
Verification of the security of computer networks: Vulnerability Assessment
A vulnerability assessment is the process of running automated tools against defined IP addresses to identify vulnerabilities in the environment in which one operates. Vulnerabilities typically include unprotected or misconfigured systems. The tools used to perform vulnerability scans are specific software that automates the process. Obviously these software are practically useless without an operator who knows how to use them correctly.
These tools provide an easy way to scan for vulnerabilities and there are both open source and proprietary ones. The main advantage of the open-source ones is that, with great probability, they are the same ones used by hackers, they are unlikely to pay an expensive subscription, when they can download open source applications for free.
In practice, a VA allows you to:
identify and classify security holes in the computer network
understand the cyber threats to which the company is exposed
recommend corrective measures to eliminate the weaknesses found
The purpose of a Vulnerability Assessment is to identify known vulnerabilities so that they can be corrected. Scans are typically done at least quarterly, although many experts recommend monthly scans.
How to perform a VA
Il processo di esecuzione si divide in due fasi e non prevede lo sfruttamento delle debolezze riscontrate. Questo ulteriore passaggio e’ invece previsto nel Penetration Test.
- Fase 1: prima analisi
- durante questa fase vengono raccolte tutte le informazioni disponibili sull’obiettivo per determinare quali potrebbero essere i punti deboli e le falle nel sistema di sicurezza delle reti informatiche
- Fase 2: seconda analisi
- in questa fase, tramite l’uso delle informazioni ricavate, vengono messe alla prova i possibili problemi. In questa fase le vulnerabilita’ sono testate per capire se siano effettivi problemi come supposto precedentemente.
Data l’incredibile velocita’ in cui le tecnologie e le tecniche informatiche si evolvono, e’ possibile che un sistema si mostri sicuro questo mese, ma abbia invece delle criticita’ da risolvere il mese successivo. Per questo e’ consigliato ripetere regolarmente e con frequenza i controlli di sicurezza sulle reti informatiche aziendali.
The execution process is divided into two phases and does not involve exploiting the weaknesses found. This further step is instead foreseen in the Penetration Test.
Phase 1: first analysis
during this phase, all the information available on the objective is collected to determine what could be the weak points and gaps in the security system of computer networks
Phase 2: second analysis
in this phase, through the use of the information obtained, possible problems are put to the test. In this phase the vulnerabilities are tested to understand if they are actual problems as previously assumed.
Given the incredible speed at which computer technologies and techniques evolve, it is possible that a system will prove secure this month, but instead have some problems to solve the following month. For this reason, it is advisable to repeat the security checks on company computer networks regularly and frequently.
At the end of the process of verifying the vulnerabilities of a system, the final reports contain all the results collected. Typically these enclose all relevant information, including:
the list of vulnerabilities found
an in-depth description of the vulnerabilities
countermeasures to be adopted to reduce risks
Verification of vulnerabilities is a fundamental procedure for the company, but it does not guarantee the security of computer networks. For the correct maintenance of the security of your systems, it is also essential to use another tool: the Penetration Test.
The Pentest, or penetration test, is aimed at verifying how the vulnerabilities of a system can be exploited to gain access and move within it. One of the initial steps performed by a pentester is scanning the network to find IP addresses, device type, operating systems and possible system vulnerabilities. But unlike the Vulnerability Assessment, the Pentest doesn’t stop there.
Of crucial importance for a tester is the exploit of identified vulnerabilities in order to gain control of the network or to take possession of sensitive data. The tester uses configurable automated tools to perform exploits against computer network systems. The peculiar part, however, occurs when the tester performs manual exploit attempts, just like a hacker would.
Penetration tests are classified in two ways: gray box or black box.
Gray box tests are performed with full knowledge of the target company’s IT department. Information is shared with the tester, such as network diagrams, IP addresses, and system configurations. The approach of this method is the verification of the safety of the present technology.
A black box test, on the other hand, represents more properly the action of a hacker who tries to gain unauthorized access to a system. The IT department knows nothing about the test being performed and the tester is not provided with information about the target environment. The black box method evaluates both the underlying technology and the people and processes involved to identify and block an attack as it would happen in the real world.
Phases of the Pentest
Phase 1: Analysis
The system is analyzed, studying its strengths and weaknesses. All preliminary information is collected. This, of course, does not happen if it is a gray box pentest.
Phase 2: Scan
The entire infrastructure is scanned to find the weak points to focus on.
Phase 3: Planning
Thanks to the information gathered, we plan with which tools and techniques to use to hit the system. The possibilities are many and they are both purely technological and social engineering techniques.
Phase 4: actual attack
In this phase the testers try to exploit the identified vulnerabilities to gain full control of the targeted system.
At the end of the Penetration Test, a report is also compiled that details the entire process carried out and includes:
evaluation of the impact of a real attack on the company
solutions to solve problems and secure computer network systems
A Penetration Test that is not successful is a sign that the system under examination is safe * and the data inside it does not risk anything. However, this does not mean that the company will be protected forever from any attack: precisely because the strategies of hackers constantly evolve, it is important to carry out Penetration Tests regularly.
(*) It should be noted, however, that although a good Penetration Test follows guidelines or structuring methodologies (i.e. OWASP) it remains a test with a strong subjective impact of the Penetration Tester and of the team that performed it, therefore it cannot be excluded that by repeating the tests carried out by a different group of Penetration Tester we have no new results. Furthermore, as is well known to our readers, in the field of Cyber Security the concept of “safe” in absolute terms is inadequate.
How to do
Although Vulnerability Assessments and Penetration Tests have different objectives, both should be performed regularly to verify the overall security of the information system.
Vulnerability assessment should be done often to identify and fix known vulnerabilities. The Pentest should be carried out at least once a year and certainly after significant changes in the IT environment, to identify possible exploitable vulnerabilities that may allow unauthorized access to the system. Both of the services described in this article are available through SOD, even on a recursive basis to ensure test effectiveness. contact us to find out more.
Security: pentest and verification of vulnerabilities
Vulnerability Assessment & Penetration Test
The computer security of a system is very important to avoid unpleasant inconveniences due to malicious attacks. In principle, it is not enough to set up a complete security system, you must also check that the above systems are working. To do this we turn to professionals who can carry out pentest (penetration tests) and carry out a vulnerability check.
To verify the security of a system, two specific procedures are used. The first, the verification of vulnerabilities, deals with researching and listing the possible breaches in the infrastructure. The second, the Penetration Test (PenTest), seeks to exploit the weaknesses identified to gain access to a closed system.
In essence it is a question of doing what an attacker would do: use his tools by checking their effectiveness or not on the security system. If these operations are carried out in a controlled environment, it will be possible to take measures before a real harmful intrusion occurs.
Known as vulnerability assessment or VA, it is the process of identifying threats and vulnerabilities on a specific machine or network.
The process tends to take place in the following phases:
Analysis of the characteristics
Using automatic software to speed up the process, one identifies the general characteristics of a target.
Identification of weak points
We identify which are the weak points that could be exploited to hit the target.
Specific manual tests
Sometimes a series of manual tests are carried out with specific tools. This is to further assess the security of specific applications or networks and to verify previously detected vulnerabilities.
Writing a report
After identifying the weak points of a goal, a document is drawn up stating the results.
A vulnerability check is important if understood as a proactive check carried out cyclically. Discovering vulnerabilities in order to be able to repair the identified problems is essential in the context of a security management program.
A serious security management program also includes penetration tests. However, the latter will be required less frequently than the VA. Vulnerability verification should be performed frequently. Only in this way can you be sure to immediately identify the weak points of a system and reduce the chances of a successful attack.
A penetration test, or PenTest, consists of a series of manual processes. In general, the ultimate goal of an ethical hacker carrying out such a test is to gain unauthorized access to a target. To do this, vulnerabilities discovered in the verification phase are also used.
A pentest is often required in various scenarios which may include:
– the launch of a new application
– a major change or update of the network
– adaptation to new compliance regulations
– a violation due to a targeted attack
Since there are various reasons for conducting a pentest, the goals you set yourself can often differ widely.
Who usually performs a pentest / VA?
The technicians who deal with it are hackers, obviously the so-called white-hats, those who exploit their knowledge for good. A pentester team may however have an extremely diverse background in education and experience.
What I really care ‘that all have one thing in common: a passion for safety and great curiosity’ to find and test the weaknesses of a system.
Could the work be automated?
The short answer is: yes and no. There are some phases that take place automatically and others that require the intervention of a technician.
The main stage of a vulnerability assessment is carried out by an automated application that will perform checks on a network, application or code. The whole execution of this phase is automatic. However, setting up this step and subsequent reporting are all manual actions.
In addition, a pentest requires much more manual labor and cannot be automated. It can happen, in fact, that during a pentest there are new breaches that had not been identified before.
Most of a pentest is the result of manual labor by testers. The software used can only provide data which will then be analyzed in depth by the technicians.
The manual test of a large application can take a lot of time, resources and a lot of previous knowledge on the architecture of the web-apps and on the test frameworks used.
The issue of security usually comes to the surface only when it is too late and an attack has already been carried out. If there is a need to manage sensitive data, complex networks or simply want to be sure not to suffer damage, planning infrastructure verification actions is vital.
