ルーターがインターネットに接続するたびに、ルーターのファイアウォールログへの侵入に関する警告が表示されます。それが何を意味するのか説明してもらえますか?それは実際に誰かが私のルーターをハッキングしているのですか、それともその接続がルーターによって切断されているのですか?
例えば.

オンライン中にいつでもポートスキャンの対象となるのは完全に正常です。これは不幸な真実です。それでも、脆弱なサービスがインターネットに公開されていない限り、これによるリスクはありません。
あなたが見ているのは単なる情報メッセージです。害はなく、ハッキングも試みられていません。
侵入ではなく、誰かがルーターを外部からスキャンして、開いているポートを見つけようとしたことを意味します。私はそれについてあまり心配しません:)
通常、ルーターでは、ネットワークへのポート(より良いWordがないため、「ゲートウェイ」と考えてください)は閉じられています。これらのポートは、さまざまな理由(独自のWebサイトのホスティングなど)で手動で開くことができます。
「ハッカー」は、これらの開いているポートをスキャンして、PCへのルートを見つけようとします。これらを手動で開いていない場合は、完全に問題ないはずです。よくわからない場合は、独自のポートスキャンを実行できます ここ そして何か開いているかどうかを自分で確認してください:)
