Analyse de log : Elasticsearch vs Apache Doris

L’analyse de log est un domaine très important pour comprendre le comportement des utilisateurs. Découvrons comment Elasticsearch et Apache Doris se comparent dans ce domaine.

Les journaux : une partie majeure des actifs de données d’une entreprise

1. Logs should be collected from all sources in a timely manner. This includes both system logs and application logs.

2. Logs should be normalized, so that they can be easily searched and analyzed.

3. Logs should be stored in a secure and reliable way.

4. Logs should be analyzed in real-time, so that any suspicious activities can be detected quickly.

5. Logs should be used for data analysis, so that trends and patterns can be identified.

Le testing est une partie importante de l’actif de données d’une entreprise et apporte des avantages à celle-ci sur trois aspects : l’observabilité du système, la sécurité informatique et l’analyse des données. Les logs sont le premier recours pour le dépannage, la référence pour améliorer la sécurité du système et le gisement de données à partir duquel vous pouvez extraire des informations qui mènent à la croissance de l’entreprise.

Les logs sont les enregistrements séquentiels des événements dans le système informatique. Si vous réfléchissez à la façon dont les logs sont générés et utilisés, vous saurez à quoi devrait ressembler un système d’analyse des logs idéal :

1. Les logs doivent être collectés de toutes les sources de manière opportune. Cela inclut à la fois les logs système et les logs applicatifs.

2. Les logs doivent être normalisés, de sorte qu’ils puissent être facilement recherchés et analysés.

3. Les logs doivent être stockés de manière sûre et fiable.

4. Les logs doivent être analysés en temps réel, afin que toute activité suspecte puisse être détectée rapidement.

5. Les logs doivent être utilisés pour l’analyse des données, afin que les tendances et les modèles puissent être identifiés.

Le testing est un outil essentiel pour garantir que les logs sont collectés, normalisés, stockés et analysés correctement. En effet, le testing peut vous aider à identifier les problèmes qui peuvent affecter la qualité des données et à vérifier que les processus sont correctement mis en œuvre. Le testing peut également vous aider à déterminer si votre système est capable de réagir rapidement aux événements critiques et de détecter les activités suspectes.

Le testing peut également être utilisé pour vérifier que les données collectées sont cohérentes et complètes, afin que les analyses puissent être effectuées de manière fiable et précise. Enfin, le testing peut être utilisé pour vérifier que les données sont stockées de manière sûre et fiable, ce qui est essentiel pour une analyse des données fiable.

En conclusion, le testing est un outil essentiel pour garantir que les logs sont collectés, normalisés, stockés et analysés correctement. Il permet également de vérifier que les données collectées sont cohérentes et complètes, afin que les analyses puissent être effectuées de manière fiable et précise. Enfin, le testing peut être utilisé pour vérifier que les donné

Cybersecurity protects internet-connected devices such as hardware, software, and data from various online threats. Cybersecurity ensures that the public relies on public services and government organizations. Business requires cyber security to safeguard their data, intellectual property, and money. Cybersecurity has risen to the top priority list for businesses worldwide in recent years. Privacy legislation such as Europe’s General Data Protection Regulation and the upcoming California Consumer Privacy Act will play a larger role in CIOs’ data handling and privacy decision-making. 

The global cybersecurity market in 2021 was $216.10 billion, and by 2030 it will reach $478.68 billion at a CAGR of 9.5% during the forecast period 2021–2030.

Data privacy and protection are two imperative aspects for all businesses today as they could be prone to security breaches. Many small and medium organizations tend to ignore application security as they believe only large enterprises are targeted by hackers. However, statistics tell a different story, 43% of cybercrimes happen against small businesses.

There are several reasons behind a cyber-attack against these organizations; from old, unpatched security vulnerabilities to malware or human errors which make take them a lucrative target for attackers. So, ignoring Cyber Security can bring you on the radar of hackers even if you are a startup.

Artificial Intelligence is a growing industry powered by advancements from large tech companies, new startups, and university research teams alike. While AI technology is advancing at a good pace, the regulations and failsafes around machine learning security are an entirely different story.

Failure to protect your ML models from cyber attacks such as data poisoning can be extremely costly. Chatbot vulnerabilities can even result in the theft of private user data. In this article, we’ll look at the importance of machine learning cyber security. Furthermore, we’ll explain how Scanta, an ML security company, protects Chatbots through their Virtual Assistant Shield.

New research from the Pacific Northwest National Laboratory (PNNL) Data Sciences and Analytics Group shows that 25% of vulnerabilities appear on social media before the National Vulnerability Database (NVD). And it takes an average of nearly 90 days between a vulnerability being discussed on social media and the time it shows up in the NVD.

Vulnerabilities on Social Media

The reasons application vulnerabilities show up this often on social media before they get logged in the NVB are multiple. For developers just starting out in their career or those learning about a specific piece of software, they may not know that something is a vulnerability, that vulnerabilities need to be treated differently, and/or how to report vulnerabilities. In some cases, they may not know if the “issue” they found is a true vulnerability. Naturally, they look to the tools they regularly use when connecting with other developers—social media channels like GitHub, Twitter, and the various forums and discussions housed on Reddit.

The Threat

The recent surge in Work-From-Home, triggered by the COVID-19 crisis, is here to stay and the first sign of it is that "WFH" has been added to the alphabet soup of jargons crowding the technology industry. WFH, however, has also created a fresh set of challenges for organizations to protect their intellectual assets from cyberattacks. It’s a no-brainer to say that our home networks are far more vulnerable than enterprise networks. Companies are leveraging this crisis to meet immediate needs as well as for building more lasting, longer-term access to a variety of resources in the cloud as well as in the enterprise data center.

As the world logs on to enterprise networks from home, the demand for more secure remote access for employees is at an all-time high. Organizations must prepare for possible cyberattacks on our home IT networks to exploit its vulnerabilities. They need to monitor IT use for signs of malicious behaviour, safeguard sensitive data and assure maximum compliance with privacy and regulatory requirements. Also, the extensive use of cloud services necessitated by the COVID-19 crisis, both on-premise and public, will compel enterprises to reassess this ecosystem and take additional steps to protect it.
