🛡️ Corporate communications must be an integral part of cyber incident preparedness, working closely with the CISO to develop and execute a crisis communication plan. Preventive measures include a crisis manual, continuous internet monitoring, and established relationships with opinion leaders to preserve reputation. The article advises joint leadership by communications and IT of a compact emergency team, creation of an independently accessible emergency infrastructure (including an darksite), staged statements and prebuilt templates, and secure off-network contact lists.

🔒 This article explains how web cookies work, their classifications, and why session IDs are particularly valuable to attackers. It outlines common attack methods — including session sniffing over HTTP, cross‑site scripting (XSS), cross‑site request forgery (CSRF), and predictable session IDs — and describes specialized tracking like supercookies and evercookies. Practical advice for users and developers covers HTTPS, browser updates, cookie management, two‑factor authentication, cautious use of public Wi‑Fi, and preferring essential cookies only.

🔒 Gainesville Regional Utilities (GRU) launched a Vendor Security Risk Assessment (VSRA) program in August 2023 to vet third-party suppliers that access its smart-grid, metering, and fiber-optic systems. The intake, triage, detailed questionnaire, technical review, and centralized recordkeeping ensure vendors meet rigorous security standards before onboarding. Automation and a vendor scoring system reduced manual work by 50% and accelerated decision-making while improving compliance.

🔍 This post outlines five practical observability best practices to improve the reliability, safety, and performance of agentic AI. It defines agent observability as continuous monitoring, detailed tracing, and logging of decisions and tool calls combined with systematic evaluations and governance across the lifecycle. The article highlights Azure AI Foundry Observability capabilities—evaluations, an AI Red Teaming Agent, Azure Monitor integration, CI/CD automation, and governance integrations—and recommends embedding evaluations into CI/CD, performing adversarial testing before production, and maintaining production tracing and alerts to detect drift and incidents.

📦 This post describes how Skopeo, a daemonless CLI for container images, can streamline image management with Artifact Registry and Google Cloud CI/CD. It outlines setup steps and five practical workflows—inspect manifests, registry-to-registry copying, listing tags, promoting images, and automated verification. The article also covers security integrations with tools like Cosign and Binary Authorization, and recommends Skopeo for faster, daemonless automation in Cloud Build and related environments.

🔒 This guide consolidates practical recommendations for securing AWS CodeBuild CI/CD pipelines, emphasizing webhook configuration, trust boundaries, and least-privilege access. It warns against automatic pull request builds from untrusted contributors and prescribes push-based, branch-based, and contributor-filtered webhook patterns, plus staged rollout using Infrastructure as Code. Additional safeguards include scoped GitHub tokens, per-build IAM roles, isolated build environments, CloudTrail logging, and manual approval gates for sensitive deployments.

🔒 This second part of the guide examines three AWS file‑sharing mechanisms — CloudFront signed URLs, an Amazon VPC endpoint service backed by a custom application, and S3 Access Points — contrasting their security, cost, protocol, and operational trade‑offs. It highlights CloudFront’s edge caching and WAF/Shield integration for low‑latency public delivery, PrivateLink for fully private TCP connectivity, and Access Points for scalable IAM‑based S3 access control. The post emphasizes choosing or combining solutions based on access patterns, compliance, and budget.

🔐 This post by Swapnil Singh (updated July 28, 2025) compares AWS file-sharing options and explains security and cost trade-offs to help architects choose the right approach. Part 1 focuses on AWS Transfer Family, Transfer Family web apps, S3 pre-signed URLs, and a serverless pre-signed URL pattern (API Gateway + Lambda), outlining strengths, limitations, and pricing considerations. It emphasizes requirements gathering—access patterns, protocols, security, operations, and business constraints—and presents a decision matrix and high-level guidance for selecting a solution.

🔐 This AWS Security Blog post, republished July 30, 2025, demonstrates how to migrate an Oracle 19c Transparent Data Encryption (TDE) keystore on Amazon EC2 from a file-based wallet to AWS CloudHSM using the CloudHSM Client SDK 5. It walks through prerequisites—CloudHSM cluster, CloudHSM admin and crypto users, network connectivity—and stepwise commands to install the client and PKCS#11 library, adjust Oracle WALLET_ROOT/TDE_CONFIGURATION, and run the ADMINISTER KEY MANAGEMENT migration. The guide also covers creating an auto-login keystore, verifying V$ENCRYPTION_WALLET status, and outlines benefits such as FIPS-validated hardware, centralized management, and improved compliance.

🔒 Browser extensions can provide useful features but also expose users and organizations to significant risk. Malicious or compromised add-ons may steal credentials, session cookies, and browsing data, inject ads or malware, redirect users, or run background tasks like cryptomining. Scrutinize developer credentials and permissions, prefer official web stores, keep browsers updated, and enable security software and MFA.

🔒 Microsoft outlines a layered defense-in-depth strategy to protect systems using LLMs from indirect prompt injection attacks. The approach pairs preventative controls such as hardened system prompts and Spotlighting (delimiting, datamarking, encoding) to isolate untrusted inputs with detection via Microsoft Prompt Shields, surfaced through Azure AI Content Safety and integrated with Defender for Cloud. Impact mitigation uses deterministic controls — fine-grained permissions, Microsoft Purview sensitivity labels, DLP policies, explicit user consent workflows, and blocking known exfiltration techniques — while ongoing research (TaskTracker, LLMail-Inject, FIDES) advances new design patterns and assurances.

🔐 This AWS Security Blog post explains how to use Amazon GuardDuty to detect suspicious activity and automatically disable accounts in AWS Managed Microsoft AD. It walks through deploying a managed directory and a directory-administration EC2 instance, configuring AWS Systems Manager Run Command documents, and orchestrating those actions with AWS Step Functions triggered by Amazon EventBridge. The guide includes required permissions, testing steps using GuardDuty’s test domains, and notes on extending the automation to reset passwords or send notifications.

🔐 In this Cybersecurity Podcast episode, ESET Principal Threat Intelligence Researcher Robert Lipovsky outlines the practical skills and personality traits useful for newcomers to the field. He addresses common questions about coding ability, college degrees, and whether formal qualifications are required. Lipovsky emphasizes curiosity, persistence, and a willingness to learn alongside foundational technical skills. The discussion frames these recommendations within an evolving threat landscape and ESET’s broader career guidance.
