A false positive alert is a type of IDS alert that occurs when the IDS mistakenly identifies benign or normal traffic as malicious or suspicious, and triggers an alarm, although there is no active attack in progress. A false positive alert can be caused by various factors, such as misconfigured IDS rules, outdated signatures, network anomalies, or legitimate traffic that resembles attack patterns. A false positive alert can waste the time and resources of the security team, as they have to investigate and verify the alert, and also reduce the trust and confidence in the IDS. A false positive alert can be reduced by tuning and updating the IDS, filtering out irrelevant traffic, and using multiple detection methods. A false positive alert is the type of IDS alert Jay has received in the above scenario, as he received an event triggered as an alarm, although there is no active attack in progress.References:

FTP traffic does not provide encryption in the data transfer process, and the data transfer between the sender and receiver is in plain text. FTP stands for File Transfer Protocol, and it is a standard network protocol for transferring files between a client and a server over a TCP/IP network. FTP uses two separate channels for communication: a control channel for sending commands and receiving responses, and a data channel for transferring files. However, FTP does not encrypt any of the data that is sent or received over these channels, which means that anyone who can intercept the network traffic can read or modify the contents of the files, as well as the usernames and passwords used for authentication. This poses a serious security risk for the confidentiality, integrity, and availability of the data and the systems involved in the file transfer. Therefore, FTP is not a secure way to transfer sensitive or confidential data over the network.References:

ISO/IEC 27018 is the ISO standard that provides guidance to ensure that cloud service providers offer appropriate information security controls to protect the privacy of their customer’s clients by securing personally identifiable information entrusted to them. ISO/IEC 27018 is a code of practice for protecting personal information in cloud storage. The term for the personal data it covers is Personally Identifiable Information or PII. ISO/IEC 27018 is an addendum to ISO/IEC 27001, the first international code of practice for cloud privacy. It helps cloud service providers who process PII to assess riskand implement controls for protecting PII. ISO/IEC 27018 was created in 2014 and updated in 2019. It has the following objectives:

• Help the public cloud service provider to comply with applicable obligations when acting as a PII processor, whether such obligations fall on the PII processor directly or through contract.
• Enable the public cloud PII processor to be transparent in relevant matters so that cloud service customers can select well-governed cloud-based PII processing services.
• Assist the cloud service customer and the public cloud PII processor in entering into a contractual agreement.
• Provide cloud service customers with a mechanism for exercising audit and compliance rights and responsibilities in cases where individual cloud service customer audits of data hosted in a multiparty, virtualized server (cloud) environment can be impractical technically and can increase risks to those physical and logical network security controls in place123.
