Intellectual scanning. Keruvannya in spillage of the security program how to correct it

Currently, a large number of instrumental features have been developed that are used to automate the detection of program errors. This article will look at actions taken from them.

Static code analysis - ce analysis software security, which is carried out on the output code of the program and is implemented without any additional monitoring of the program.

Security programs often accommodate various spills through modifications in the program code. Remedies that allow programs to be disrupted may lead to program failure in certain situations, which may then be destroyed. normal robot programs: this is often caused by changes in data, changes in programs or systems. Most of the problems are associated with incorrect processing of data received from calls and insufficient verification of them.

To detect spills, various instrumental methods, such as static analyzers, are used. exit code programs, which are outlined in this article.

Classification of zakhistu spills

If the program can operate correctly and all possible input data is corrupted, a security vulnerability may arise. The spillover of protection can lead to the point that one program can be used to interfere with the protection of the entire system as a whole.

Classification of spills program pardons:

  • Buffer overflow. This spillover occurs through the lack of control over the output between the memory array and the time of program termination. If a large packet of data overflows the buffer of the limited size, the third-party memory space is overwritten, and a crash and crash from programs occurs. As the buffer is expanded in memory, the process is divided into stack buffer overflow, heap buffer overflow, and bss buffer overflow.
  • Tainted input vulnerability. The effects of "zipped entry" can arise in cases where the data entered by the user is transferred without sufficient control to the interpreter of the external language (for example, the Unix shell or SQL). In this case, the user can specify the input data in such a way that when launched, the interpreter will end up with a completely different command than the one the authors of the developed program sent.
  • Format string vulnerability. Tsey type urinary hazards are classified under the urinary classification of “zipper injection”. The fault arises from insufficient control of parameters when using the formatted input-output functions printf, fprintf, scanf, etc. of the standard language library. These functions take as one of their parameters a character string that specifies the format for entering or displaying the function's arguments. If you can specify the type of formatting, this flow may be lost as a result of the recent stoppage of the row formatting function.
  • Spilling as a result of race conditions. Problems associated with a lot of tasks lead to a situation called “race camp”: the program is not insured for the task-rich middle, it is important to remember that, for example, it is impossible to change the files that have been corrupted by it during the hour program As an inheritor, a malicious person who constantly replaces these working files can impose the program on the creation of song actions.

Of course, in addition to overinsurance, there are also other classes of spillovers.

Review of existing analyzers

To identify spillovers, the programs should use the following instrumental features:

  • Dynamic juggers. Tools that allow you to customize programs in your computer process.
  • Static analyzers (static devices). Tools that analyze information accumulated during static analysis of programs.

Static analyzers indicate these places in programs that may contain data. These suspicious code fragments can either conceal the threat or turn out to be completely harmless.

This article contains a review of several static analyzers. Let's take a look at the reports of the skins from them.

Spill management involves identifying, assessing, classifying and selecting solutions to mitigate spills. The foundation of spill management is a repository of information about spills, one of which is the “Prospective Monitoring” spill management system.

Our decision controls the appearance of information about the spill in operating systems(Windows, Linux/Unix-based), office and application software, software, information protection features.

The database of the Perspective Monitoring software distribution management system is automatically updated with the following items:

  • Data bank of threats to security information (BDU BI) FSTEC of Russia.
  • National Vulnerability Database (NVD) NIST.
  • Red Hat Bugzilla.
  • Debian Security Bug Tracker.
  • CentOS Mailing List.

We also use automation to update our vulnerability database. We have developed a web story crawler and an unstructured data parser, which is now analyzing over a hundred different foreign and Russian devices in a row key words- social media groups, blogs, microblogs, PHI, dedicated information technologies and information security. Once the tools find out what is consistent with the search, the analyst manually checks the information and enters it into the database.

Monitoring software security flaws

With the help of the Spill Management System, manufacturers can monitor the presence and occurrence of spills in third-party components of their software.

For example, in the Secure Software Developer Life Cycle (SSDLC) model from Hewlett Packard Enterprise, control of third-party libraries is one of the central places.

Our system detects errors in parallel versions/builds of the same software product.

It works like this:

1. The retailer provides us with a transfer of third-party libraries and components that are used in the product.

2. We are currently checking:

b. Where methods have appeared earlier than the manifestations of shocks.

3. The developer is informed that the status change or the vulnerability scoring corresponds to the specified role model. This means that different groups of distributors of the same company will cancel notifications and monitor the spill status only for the product on which the stench is being treated.

The frequency of notification of the spill system is adjusted sufficiently, but if a spill is detected with a CVSS score of more than 7.5, the distributors will reject the notifications.

Integration with ViPNet TIAS

The ViPNet Threat Intelligence Analytics System software and hardware system automatically detects computer attacks and detects incidents on the platform across various devices. information security. The main application for ViPNet TIAS is ViPNet IDS, which analyzes incoming and outgoing network traffic using the AM Rules global rule base for the “Advanced Monitoring” section. These signatures are written to detect the exploitation of threats.

If ViPNet TIAS detects an IB incident in which a spill was exploited, then all spill-related information, including methods for mitigating and compensating for negative spills, is automatically entered into the incident card from the control system.

The incident management system also assists in the investigation of information security incidents by providing analysts with information about indicators of compromise and potential breaches of the university information infrastructure.

Monitoring the presence of vulnerabilities in information systems

Another scenario for a faulty spill control system is a re-verification.

Zamovnik independently forms the transfer installed on nodes (workstation, server, DBMS, PAK SZI, Merezheve obladnannya) system and application software components, transmits this flow to the control system and receives information about spill detection and periodic notifications about their status.

System features for advanced spill scanners:

  • Does not require installation of monitoring agents on nodes.
  • It does not create a focus on the border, fragments of the architecture itself are not transferred to the agents and scanning servers.
  • It does not create the advantage of ownership, some of the components are created by system commands and a lightweight script with a closed source code.
  • Enables the flow of information. “Prospective monitoring” cannot reliably know anything about the physical, logical development or functional significance of a node in an information system. The only information that is included between the controlled perimeter of the locker is a txt file containing a mixture of software components. This file is checked for replacement and stored in the control system by the deputy himself.
  • For the robotic system, we do not need cloud records on control nodes. The information is collected by the node administrator under the name.
  • Secure information exchange ViPNet VPN, IPsec or https.

Connection to the “Prospective Monitoring” spill management service helps the deputy manager of the Vikonati group ANZ.1 “Spill detection and analysis” information systemі more quickly"new emergencies" instructions of the FSTEC of Russia No. 17 and 21. Our company is a licensee of the FSTEC of Russia to operate under the technical protection of confidential information.

Another way to look at this problem is that companies have a responsibility to react quickly when a program is spilled. This ensures that the IT department is able to remain consistent installed programs, components and patches for additional automation features and standard tools. There is a need for standardization of software tags (19770-2), which are XML files installed with an addendum, component and/or patch, which identify the installed software, and in some cases the component Cha, what an additional stench is partly. Tags contain authoritative information about the type, information about the version, a list of files with the file name, a secure hash of the file and the size that can be used to confirm that the installed add-ons are in the system, and what The files have not been modified by a third party. Subscribe to these tags digital signature Vidavets.

If there is a spill, IT departments can use their security software to securely identify systems from the spilled software and can create time to update systems. Tags may be part of a patch or an update, which you can check to see what the patch is installed. Thus, IT organizations can use resources such as the NIST National Risk Database to manage their asset management tools, so that only the spill will be sent to the company in NVD, IT department can safely equalize new spills from them until now.

The main group of companies working through an IEEE/ISTO non-profit organization called TagVault.org (www.tagvault.org) in the United States is working on a standard implementation of ISO 19770-2 to enable this level of automation. At some point, these tags that indicate this implementation, which will mean everything, will be binding for software sold to the US government at some point in the near future.

Therefore, it is a good practice not to publish about those add-ons and specific versions of the software you are using, otherwise it may be difficult, as was stated earlier. Do you want to make sure that you have an accurate, up-to-date software security inventory, that you regularly check the list of common problems, such as NVID and NVD, and that your IT department can do a lot of work for you? There are threats, this is in order with new revelations Intrusion, anti-virus scans and other methods of blocking the middle, it will be even more difficult to compromise your middle, and if/when this happens, it will not be revealed for the next three hours.

On startup intelligent scanning Avast program scan your PC for these types of problems, and then suggest options for eliminating them.

  • Viruses: files that remove malicious code that can affect the safety and productivity of your PC.
  • Vrazliv PZ: Programs that require updating and may be subject to malware in order to gain access to your system.
  • Browser extensions bad reputation : Browser extensions that can be installed without your permission and impact system productivity.
  • Untrusted passwords: passwords that are used to access up to one regional registration on the Internet they can be easily hacked or compromised.
  • Merezhevi threats: the effects of your measures, which can lead to possible attacks on your edge structures that router.
  • Productivity problems: objects ( Unnecessary files and programs, problems related to settings) that can interfere with your PC.
  • Conflicting antiviruses: anti-virus programs installed on the PC directly from Avast. The presence of many antivirus programs Increases PC performance and reduces the effectiveness of anti-virus protection.
