op Spearphishing belangrijke aanvalsvector voor ransomware -- Beveiliging je mailinfrastructuur met SPF/DKIM/DMARC en DANE "Spear phishing blijkt na 'remote desktop'-diensten de op-een-na grootste aanvalsvector voor ransomware te zijn. Bovendien wint phishing aan terrein als eerste ingang voor kwaadwillenden. Het goede nieuws is dat de toepassing van moderne beveiligingsstandaarden voor mail het risico op phishing sterk kunnen verminderen."

op Agressief cache-gebruik levert snelheidswinst en efficiëntie op voor validerende resolvers -- Oude bug in F5-software resulteert in wekenlange zoektocht "RFC 8198 beschrijft een mechanisme voor het hergebruik van NSEC(3)- en wildcard-records in de cache van validerende resolvers. Door eerst te checken of een domeinnaam binnen het bereik van een al aanwezig record valt, kunnen nieuwe DNS(SEC)-query’s uitgespaard worden."

op Versleuteld DNS-verkeer sneller en efficiënter met nieuw DNS-over-QUIC-protocol -- Eerste brede implementaties onderweg
"Het probleem dat QUIC oplost is het (tijdelijke) blokkeren van de netwerkverbinding als een TCP-pakket onderweg verloren gaat of vertraagd wordt. Kenmerkend onderscheid van TCP ten opzichte van UDP is immers dat de inhoud van TCP-pakketten compleet en in volgorde afgeleverd wordt bij het eindpunt (i.e. een doorlopende dataverbinding)."

now also available in English: IPv4 address prices go through the roof -- "IPv6 adoption needs to really speed up" Freedom Internet believes its competitiveness is affected by the ongoing address problem: "Retail margins are tight, and what we pay for IPv4 addresses is an additional cost item that feeds into our pricing model. So we're inevitably a little more expensive than a rival without that cost."
