Problématique
Intrusion detection is essential for organizations to safeguard their systems against threats arising from network connectivity and reliance on IT infrastructure Given the evolving landscape of modern security threats, it raises the question of whether organizations need to implement intrusion detection systems Additionally, it is crucial to consider the specific features and capabilities that should be utilized in these systems to effectively enhance security.
Intrusion Detection Systems (IDS) have gained recognition as essential components of every organization's security infrastructure Despite the documented benefits that IDS technologies provide to security systems, many organizations still need to justify their investment in these solutions.
Connecting your computer to the internet always carries risks, including potential data loss or theft Malicious hackers exploit vulnerabilities in services, applications, and networks to attack your system Therefore, it is essential to implement effective strategies for monitoring and controlling the data packets flowing through the network.
Pour réaliser cette idée, il est obligatoire de comprendre quelle est l’intrusion?
Comment fonctionne il sur le réseau? À partir de cela, vous pouvez choisir telle solution pour votre système
As part of my internship at UQAM focused on cybersecurity, the issue at hand revolves around the complexities of information security systems While the concepts related to this topic are relatively easy to define and understand, the challenge lies in their practical implementation Thus, the central question addresses the critical aspects of cybersecurity.
Résultats antérieurs
Due to malicious activities, the development of computer networks has heavily relied on cybersecurity organizations such as NAS, ISS, and SAN Thanks to cybersecurity experts, our computers and systems face reduced risks while navigating the Internet, significantly lowering exposure to threats They have developed numerous effective methods and tools to detect and combat hackers and other malicious acts.
Today, computer scientists inherit valuable knowledge in the field of cybersecurity, with information readily available online Therefore, mastering intrusion analysis techniques and applying them in real-life scenarios is essential My role focuses on understanding concepts and software implemented on hosts or workstations to detect and prevent intrusions aimed at attacking computer systems or networks.
Système de détection des intrusions
Définition
Intrusion detection is the process of monitoring events within a computer system or network to identify signs of unauthorized access or attempts to compromise confidentiality, integrity, and availability Intrusions can result from attacks that exploit vulnerabilities through the Internet, unauthorized users attempting to gain additional privileges, or authorized users abusing their granted access An intrusion detection system (IDS) is a software or hardware solution that automates the monitoring and analysis processes to enhance security.
Pourquoi a-t-on besoin de l’IDS?
Installing an Intrusion Detection System (IDS) in your network is essential for monitoring packet traffic Think of the IDS as a camera positioned at your network's entrance, allowing you to identify potential attackers attempting to breach your system.
When a successful attempt bypasses your firewall, it can lead to potential threats Understanding these attempts can help reduce false positives In a NAT environment, this is beneficial as it allows us to correlate the real source address with events in the IDS system located before and after the firewall.
This topology allows you to verify whether your firewall baseline is being followed or if an error has occurred due to a change in firewall rules For instance, if your firewall baseline prohibits the use of FTP and your IDS system triggers FTP alerts, it indicates that the firewall is not blocking FTP traffic However, this should not be the sole method for ensuring compliance with your baseline.
Types majeurs de l’IDS
There are various types of Intrusion Detection Systems (IDS) available today, each characterized by different monitoring methods and analytical approaches Each approach comes with its own set of advantages and disadvantages Furthermore, all these approaches can be described within the framework of a general process model for IDS.
Plusieurs IDS peuvent être décrits dans un terme de trois composants des fonctions fondamental :
Information sources play a crucial role in determining whether an intrusion is active or not These sources can be derived from various levels of the system, including the network, server center, and commonly monitored applications.
The analysis component of an intrusion detection system is responsible for organizing and interpreting sensitive events derived from information sources It determines whether these events indicate that an intrusion is occurring or has already taken place The most common analytical approaches include the detection of malicious and anomalous activities.
The system's actions for detecting intrusions are categorized into active and passive measures Active measures involve automated interventions within the system, while passive measures generate reports from the Intrusion Detection System (IDS) that require human review for further action based on those findings.
Source des informations
• Le NIDS peut surveiller un grand réseau
The deployment of Network Intrusion Detection Systems (NIDS) has minimal impact on existing networks Typically, NIDS are passive devices that monitor network traffic without interfering with normal operations Consequently, integrating an IDS into a network can be achieved with minimal effort, making it a straightforward process to enhance network security.
• NIDS peut être très sûr contre l'attaque et être même se cache à beaucoup d'attaquants
• Il est difficile à traiter tous les paquets circulant sur un grand réseau De plus il ne peut pas reconnaợtre des attaques pendant le temps de haut trafic
• Quelques fournisseurs essayent à implémenter le IDS dur le matériel pour qu’il marche plus rapidement
Many of the advantages of Network Intrusion Detection Systems (NIDS) cannot be utilized with modern switches Most switches do not offer universal port monitoring, which limits the monitoring capabilities of NIDS Even when switches do provide monitoring ports, a single port often fails to reflect all the traffic passing through the switch.
• NIDS ne peut pas analyse des informations chiffrées (cryptées) Ce problème a lieu dans les organisations utilisant le VPN
• La plupart de NIDS ne peuvent pas indiquer si un attaque réussi ou non Il reconnaợt seulement que un attaque est initialisộ C'est-à-dire qu’aprốs le
NIDS détecte une attaque, l’administrateur doit examiner manuellement chaque host s’il a été en effet pénétré
• Quelques NIDS provoque des paquets en fragments Ces paquets mal formés font devenir le IDS instable et l'accident
Host Intrusion Detection Systems (HIDS) operate by collecting information from individual computer systems, enabling reliable and precise analysis of activities This capability allows for the accurate identification of the processes and users involved in specific attacks on the operating system Furthermore, HIDS can monitor outgoing attempts, as they have direct access to and oversight of data and processes targeted by these attacks.
HIDS typically utilizes two types of information sources: audit trails from the operating system and system logs The audit trail generated at the kernel level of the operating system is more detailed and secure compared to system logs However, system logs are less complex and more concise, making them easier to interpret.
Some Host Intrusion Detection Systems (HIDS) are designed to support centralized management of IDS, providing an infrastructure that enables a user-friendly management console for monitoring multiple hosts Additionally, the generated messages are formatted to be compatible with network management systems.
• Pouvoir surveiller des événements local jusqu’au host, détecter des attaques qui ne sont pas vues par NIDS
Navigating an environment where network traffic is encrypted requires understanding that host-based information sources are generated either before the data is encrypted or after it is decrypted at the destination host.
• HIDS n’est pas atteint par le réseau commuté
• Lors que HIDS marche sur la traợnộ de l’audit de SE, ils peuvent dộtecter le
Cheval de Troie ou les autres attaques concernant à la brèche intégrité de logiciel
• HIDS est difficile à gérer, et des informations doivent configurées et gérées pour chaque host surveillé
Since some information sources for Host Intrusion Detection Systems (HIDS) are based on the destination host during attacks, the IDS itself can be targeted and neutralized as part of the overall attack strategy.
• HIDS n’est pas bon pour le balayage de réseau de la détection ou les autre tel que la surveillance qui s’adresse au réseau entier parce que le
HIDS ne voit que les paquets du rộseau reỗus par ses hosts
• HIDS peut être neutralisé par certaine attaque de DoS
When HIDS utilizes system audit trails as information sources, the volume of data generated is substantial, necessitating additional local storage within the system.
SNORT
1 Qu’est ce que SNORT?
SNORT is an open-source network intrusion detection system capable of real-time traffic analysis on IP networks It performs protocol analysis by inspecting and matching content, making it effective in detecting a wide range of attacks, including buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and more.
SNORT utilizes a flexible rule-based language to define the traffic it should capture or ignore, along with a detection engine that employs a modular plug-in architecture It offers real-time alerting capabilities, incorporating alert mechanisms for event systems, user-defined logs, Unix sockets, or WinPopup messages to Windows clients using smbclient.
SNORT has three primary uses: it can function as a packet sniffer similar to tcpdump, serve as a packet logger beneficial for analyzing network traffic, and operate as a comprehensive network intrusion detection system.

Système d’empêchement des intrusions
Qu’est ce que le IPS ?
The intrusion prevention system is designed to block attacks as they occur, while the detection system focuses on identifying intrusions and alerting users Both systems rely on advanced analysis to detect and prevent malicious activities effectively.
Le système d’empêchement d’intrusion construit sa part à résoudre le problème
A zero-day attack occurs when vulnerabilities in your system are exploited, making it crucial to find a rapid solution During this critical moment, Intrusion Prevention Systems (IPS) become invaluable in safeguarding your network.
L’IPS est une rộponse industrielle aux clients qui demandent la question ô Pourquoi nous n’empờchons pas des attaques quand nous les dộtectons? ằ
Source : http://wp.bitpipe.com/resource/org_1046366622_812/IPS_Whitepaper.pdf
Qu’est ce que le Zero day exploits
Zero-day exploits represent a significant challenge in information security, as they are unknown vulnerabilities that are difficult to detect Attackers invest considerable time in uncovering these vulnerabilities to exploit sensitive information Fortunately, information security professionals have a powerful ally in the form of "best practices." These best practices consist of a combination of security tools and methodologies designed to defend against the daily threats posed by scans, worms, and compromise attempts The effectiveness of these two strategies in combating zero-day exploits is crucial for maintaining robust security.
Zero-day exploits are vulnerabilities in software, execution, or specific protocols discovered by attackers They create code to exploit these vulnerabilities and compromise systems These exploits are highly sought after by cybercriminals and are traded like valuable natural resources for other private exploits, typically through Internet Relay Chat channels or private underground websites.
Source: http://www.itworld.com/nl/security_strat/10302002/pf_index.html
Qu’est ce que Zero-day Protection?
Jusqu’au présent, je n’ai pas encore trouvé une définition complète de Zero-day
Protection against zero-day exploits is crucial, as these vulnerabilities can be exploited by attackers It is essential to identify and address these vulnerabilities promptly to safeguard systems and data from potential threats.
En fait, il y a des différences entre le “Zero-day exploits” et le Zero-day vulnérabilité
Le “Zero-day exploits” exploite une vulnérabilité inconnue, tandis que le Zero-day vulnộrabilitộ est les trous dans un logiciel que personne ne connaợt b) Spécification
When an attacker exploits a vulnerability in software or a system, they often disclose this information publicly If the vendor fails to mitigate the exploit or fix the vulnerability, it can lead to additional attacks on the system This situation is referred to as a "Zero-day" vulnerability.
Par exemple, un des types de MyDoom a apparaợt aprốs 2 jours quand il y avait une vulnérabilité dans l’application Internet Explorer, ce n’est pas longtemps c) Fonctionnements
Vulnerabilities can become widely recognized in various ways, such as when a victim analyzes the exploit that compromised their system and publicly discloses the previously unknown weakness Alternatively, these vulnerabilities may remain within underground professional circles, evading security measures for a time Once a vulnerability is known, it can evolve into automated malware tools or lead to further discoveries Additionally, vendors may not respond immediately with a patch or fix, creating a gap between the awareness of the vulnerability and its resolution Consequently, it is crucial for security personnel to minimize this gap as much as possible.
Best practices serve as the baseline for conducting vulnerability assessments and should be applied to all systems and network assets Even if an attacker uses a zero-day exploit to compromise a system, security personnel are typically alerted by an intrusion detection system, which is a key component of most network best practices Additionally, access is minimized by other security mechanisms that remain intact and unaffected by the exploit.
While numerous "best practice" tools are available, they often promote entirely different methodologies and mechanisms for achieving a balance between safety and profitability This discrepancy complicates the assessment of who faces the greatest challenges and who reaps the most significant rewards For instance, are the insights from the SANS Institute superior to those from the Center for Security Ideas?
Regardless of the tools you choose, implementing best security practices across the organization is essential; otherwise, an attacker may discover a vulnerable system, potentially leading to significant financial damage Furthermore, an attacker's exploit could target a system critical to maintaining a company's security, resulting in a substantial compromise.
It's essential to recognize that "zero-day exploits" will always pose a threat, as attackers may possess knowledge that we do not While there is little we can do to defend against the unknown, implementing best practices can help minimize potential damage when such threats arise The key to effectively utilizing best practices lies in selecting and managing them appropriately Carefully choose practices that align with your organization's risk tolerance, security policies, and overall attitude towards security.
Zero-day exploits occur when an attacker takes advantage of security vulnerabilities on the same day they become known Typically, once a potential exposure is detected in an application or software, the individual or organization can notify the software company, allowing them to address the issue and protect against exploitation In due time, the software company can develop and distribute a fix to users However, potential intruders also become aware of these vulnerabilities, which underscores the urgency of timely reporting and remediation.
With experience, intruders can quickly exploit vulnerabilities, and sometimes they may be the first to discover them In such cases, both the vulnerability and the exploit can become apparent on the same day Since the vulnerability is not known in advance, it is impossible to guard against the exploit before it occurs However, companies exposed to such exploits can implement procedures for early detection of an exploit.
